2019-09-03usb: host: xhci-rcar: Use xhci_plat_priv.quirks instead of code settingsYoshihiro Shimoda
This patch uses xhci_plat_priv.quirks to simplify. The previous code had conditions to set some quirks in xhci_rcar_init_quirk(). But, the xhci_rcar_init_quirk() is called at the same conditions. So, no behavior change.

2019-09-03Revert "rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band"Stanislaw Gruszka
This reverts commit 9ad3b55654455258a9463384edb40077439d879f. As reported by Sergey: "I got some problem after upgrade kernel to 5.2 version (debian testing linux-image-5.2.0-2-amd64). 5Ghz client stopped to see AP. Some tests with 1metre distance between client-AP: 2.4Ghz -22dBm, for 5Ghz - 53dBm !, for longer distance (8m + walls) 2.4 - 61dBm, 5Ghz not visible." It was identified that rx signal level degradation was caused by 9ad3b5565445 ("rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band"). So revert this commit.

2019-09-03xhci: fix possible memleak on setup address fails.Ikjoon Jang
Xhci re-enables a slot on transaction error in set_address using xhci_disable_slot() + xhci_alloc_dev(). But in this case, xhci_alloc_dev() creates debugfs entries upon an existing device without cleaning up old entries, thus memory leaks. So this patch simply moves calling xhci_debugfs_free_dev() from xhci_free_dev() to xhci_disable_slot().

2019-09-03zd1211rw: zd_usb: Use struct_size() helperGustavo A. R. Silva
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct usb_int_regs { ... struct reg_data regs[0]; } __packed; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following function: static int usb_int_regs_length(unsigned int count) { return sizeof(struct usb_int_regs) + count * sizeof(struct reg_data); } with: struct_size(regs, regs, count) This code was detected with the help of Coccinelle.

2019-09-03brcmfmac: get chip's default RAM info during PCIe setupRafał Miłecki
Getting RAM info just once per driver's lifetime (during chip recognition) is not enough as it may get adjusted later (depending on the used firmware). Subsequent inits may load different firmwares so a full RAM recognition is required on every PCIe setup. This is especially important since implementing hardware reset on a firmware crash. Moreover calling brcmf_chip_get_raminfo() makes sure that RAM core is up. It's important as having BCMA_CORE_SYS_MEM down on BCM4366 was resulting in firmware failing to initialize and following error: [ 65.657546] brcmfmac 0000:01:00.0: brcmf_pcie_download_fw_nvram: Invalid shared RAM address 0x04000001 This change makes brcmf_chip_get_raminfo() call during chip recognition redundant for PCIe devices but SDIO and USB still need it and it's a very small overhead anyway.

2019-09-03rt2x00: do not set IEEE80211_TX_STAT_AMPDU_NO_BACK on tx statusStanislaw Gruszka
According to documentation IEEE80211_TX_STAT_AMPDU_NO_BACK is suppose to be used when we do not recive BA (BlockAck). However on rt2x00 we use it when remote station fail to decode one or more subframes within AMPDU (some bits are not set in BlockAck bitmap). Setting the flag result in sent of BAR (BlockAck Request) frame and this might result of abuse of BA session, since remote station can sent BA with incorrect sequence numbers after receiving BAR. This problem is visible especially when connecting two rt2800 devices. Previously I observed some performance benefits when using the flag when connecting with iwlwifi devices. But currently possibly due to reacent changes in rt2x00 removing the flag has no effect on those test cases. So remove the IEEE80211_TX_STAT_AMPDU_NO_BACK.

In commit 98fd8db59a00 ("rtlwifi: rtl8192ce: Convert macros that set descriptor"), all the routines that get fields from a descriptor were changed to return signed integer values. This is incorrect for the routines that get the entire 32-bit word. In this case, an unsigned quantity is required.

2019-09-03rtlwifi: rtl8192cu: Convert inline routines to little-endian wordsLarry Finger
In this step, the read/write routines for the descriptors are converted to use __le32 quantities, thus a lot of casts can be removed. Callback routines still use the 8-bit arrays, but these are changed within the specified routine.

2019-09-03rtlwifi: rtl8192cu: Convert macros that set descriptorLarry Finger
As a first step in the conversion, the macros that set the RX and TX descriptors are converted to static inline routines, and the names are changed from upper to lower case. To minimize the changes in a given step, the input descriptor information is left as as a byte array (u8 *), even though it should be a little-endian word array (__le32 *). That will be changed in the next patch. Several places where checkpatch.pl complains about a space after a cast and other warnings are fixed.

2019-09-03rtlwifi: rtl8192cu: Replace local bit manipulation macrosLarry Finger
This driver uses a set of local macros to manipulate the TX and RX descriptors, which are all little-endian quantities. These macros are replaced by the bitfield macros le32p_replace_bits() and le32_get_bits(). In several places, the macros operated on an entire 32-bit word. In these cases, a direct read or replacement is used. Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-09-03hypfs: don't bother with d_delete()Al Viro
If that's not the last reference, d_delete() will do d_drop(). If it is, dput() immediately after it will unhash the sucker anyway, since ->d_delete() the method is always_delete_dentry(). IOW, there's no point trying to turn it into a negative hashed dentry - it won't stick around anyway. Just d_drop() it and be done with that. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
