2016-07-04cdc_ncm: workaround for EM7455 "silent" data interfaceBjørn Mork
Several Lenovo users have reported problems with their Sierra Wireless EM7455 modem. The driver has loaded successfully and the MBIM management channel has appeared to work, including establishing a connection to the mobile network. But no frames have been received over the data interface. The problem affects all EM7455 and MC7455, and is assumed to affect other modems based on the same Qualcomm chipset and baseband firmware. Testing narrowed the problem down to what seems to be a firmware timing bug during initialization. Adding a short sleep while probing is sufficient to make the problem disappear. Experiments have shown that 1-2 ms is too little to have any effect, while 10-20 ms is enough to reliably succeed.

2016-07-04Revert "gpiolib: Split GPIO flags parsing and GPIO configuration"Johan Hovold
This reverts commit 923b93e451db876d1479d3e4458fce14fec31d1c. Make sure consumers do not overwrite gpio flags for pins that have already been claimed. While adding support for gpio drivers to refuse a request using unsupported flags, the order of when the requested flag was checked and the new flags were applied was reversed to that consumers could overwrite flags for already requested gpios. This not only affects device-tree setups where two drivers could request the same gpio using conflicting configurations, but also allowed user space to clear gpio flags for already claimed pins simply by attempting to export them through the sysfs interface. By for example clearing the FLAG_ACTIVE_LOW flag this way, user space could effectively change the polarity of a signal. Reverting this change obviously prevents gpio drivers from doing sanity checks on the flags in their request callbacks. Fortunately only one recently added driver (gpio-tps65218 in v4.6) appears to do this, and a follow up patch could restore this functionality through a different interface.

2016-07-04gpio: sch: Fix Oops on module load on Asus Eee PC 1201Colin Pitrat
This fixes the issue descirbe in bug 117531 (https://bugzilla.kernel.org/show_bug.cgi?id=117531). It's a regression introduced in linux 4.5 that causes a Oops at load of gpio_sch and prevents powering off the computer. The issue is that sch_gpio_reg_set is called in sch_gpio_probe before gpio_chip data is initialized with the pointer to the sch_gpio struct. As sch_gpio_reg_set calls gpiochip_get_data, it returns NULL which causes the Oops. The patch follows Mika's advice (https://lkml.org/lkml/2016/5/9/61) and consists in modifying sch_gpio_reg_get and sch_gpio_reg_set to take a sch_gpio struct directly instead of a gpio_chip, which avoids the call to gpiochip_get_data.

2016-07-04ovl: Copy up underlying inode's ->i_mode to overlay inodeVivek Goyal
Right now when a new overlay inode is created, we initialize overlay inode's ->i_mode from underlying inode ->i_mode but we retain only file type bits (S_IFMT) and discard permission bits. This patch changes it and retains permission bits too. This should allow overlay to do permission checks on overlay inode itself in task context. [SzM] It also fixes clearing suid/sgid bits on write.

2016-07-04ovl: handle ATTR_KILL*Miklos Szeredi
Before 4bacc9c9234c ("overlayfs: Make f_path...") file->f_path pointed to the underlying file, hence suid/sgid removal on write worked fine. After that patch file->f_path pointed to the overlay file, and the file mode bits weren't copied to overlay_inode->i_mode. So the suid/sgid removal simply stopped working. The fix is to copy the mode bits, but then ovl_setattr() needs to clear ATTR_MODE to avoid the BUG() in notify_change(). So do this first, then in the next patch copy the mode.

2016-07-04cpuidle: Fix last_residency divisionShreyas B. Prabhu
Snooze is a poll idle state in powernv and pseries platforms. Snooze has a timeout so that if a CPU stays in snooze for more than target residency of the next available idle state, then it would exit thereby giving chance to the cpuidle governor to re-evaluate and promote the CPU to a deeper idle state. Therefore whenever snooze exits due to this timeout, its last_residency will be target_residency of the next deeper state. Commit e93e59ce5b85 "cpuidle: Replace ktime_get() with local_clock()" changed the math around last_residency calculation. Specifically, while converting last_residency value from nano- to microseconds, it carries out right shift by 10. Because of that, in snooze timeout exit scenarios last_residency calculated is roughly 2.3% less than target_residency of the next available state. This pattern is picked up by get_typical_interval() in the menu governor and therefore expected_interval in menu_select() is frequently less than the target_residency of any state other than snooze. Due to this we are entering snooze at a higher rate, thereby affecting the single thread performance. Fix this by using more precise division via ktime_us_delta().

2016-07-04ALSA: timer: Fix negative queue usage by racy accessesTakashi Iwai
The user timer tu->qused counter may go to a negative value when multiple concurrent reads are performed since both the check and the decrement of tu->qused are done in two individual locked contexts. This results in bogus read outs, and the endless loop in the user-space side.

Since the value 65536 will not fix in a u16, the 'did' variable must be promoted to an int, otherwise the test for < 65536 will always be true and the loop will never end.

2016-07-04NFC: nfcsim: Make use of the Digital layerThierry Escande
With this complete rewrite, the loopback nfcsim driver now relies on the Digital layer of the nfc stack. As with the previous version, 2 nfc devices are declared when the driver is initialized. The driver supports the NFC_DEP protocol in NFC-A and NFC-F technologies. The 2 devices are using a pair of virtual links for sk_buff exchange. The out-link of one device is the in-link of the other and conversely. To receive data, a device calls nfcsim_link_recv_skb() on its in-link and waits for incoming data on a wait queue. To send data, a device calls nfcsim_link_send_skb() on its out-link which stores the passed skb and signals its wait queue. If the peer device was in the nfcsim_link_recv_skb() call, it will be signaled and will be able to pass the received sk_buff up to the Digital layer.

2016-07-04NFC: hci: delete unused nfc_llc_get_rx_head_tail_room()Denys Vlasenko
It used to be EXPORTed, but then EXPORT usage was cleaned up (in 2012), without noticing that the function has no users at all (and curiously, never had any users). Delete it. While at it, remove non-static "inline" hints on nearby functions: these hints don't work across compilation units anyway, and these functions are not used in their .c file, thus they are never inlined. IOW: "inline" here does not help in any way.

2016-07-04NFC: set info->ram_patch to NULL when it is releasedColin Ian King
When info->ram_patch is released info->otp_patch is being set to NULL rather than info->ram_patch. I believe this is a cut-n-paste bug from almost identical code proceeding it that uses the same idiom for info->otp_patch.
