2012-01-25drm/radeon: silence out possible lock dependency warningJerome Glisse
Silence out the lock dependency warning by moving bo allocation out of ib mutex protected section. Might lead to useless temporary allocation but it's not harmful as such things only happen at initialization.

2012-01-25drm: Fix authentication kernel crashThomas Hellstrom
If the master tries to authenticate a client using drm_authmagic and that client has already closed its drm file descriptor, either wilfully or because it was terminated, the call to drm_authmagic will dereference a stale pointer into kmalloc'ed memory and corrupt it. Typically this results in a hard system hang. This patch fixes that problem by removing any authentication tokens (struct drm_magic_entry) open for a file descriptor when that file descriptor is closed.

2012-01-25ALSA: hda - Fix silent output on ASUS A6RpTakashi Iwai
The refactoring of Realtek codec driver in 3.2 kernel caused a regression for ASUS A6Rp laptop; it doesn't give any output. The reason was that this machine has a secret master mute (or EAPD) control via NID 0x0f VREF. Setting VREF50 on this node makes the sound working again.

2012-01-24rds: Make rds_sock_lock BH rather than IRQ safe.David S. Miller
rds_sock_info() triggers locking warnings because we try to perform a local_bh_enable() (via sock_i_ino()) while hardware interrupts are disabled (via taking rds_sock_lock). There is no reason for rds_sock_lock to be a hardware IRQ disabling lock, none of these access paths run in hardware interrupt context. Therefore making it a BH disabling lock is safe and sufficient to fix this bug. Reported-by: Kumar Sanghvi <kumaras@chelsio.com> Reported-by: Josh Boyer <jwboyer@gmail.com> Signed-off-by: David S.

2012-01-24drm/radeon: finish getting bios earlierIgor Murzov
Return a number of bytes read in radeon_atrm_get_bios_chunk() and properly check this value in radeon_atrm_get_bios(). If radeon_atrm_get_bios_chunk() read less bytes then were requested, it means that it finished reading bios data. Prior to this patch, condition in radeon_atrm_get_bios() was always equivalent to "if (ATRM_BIOS_PAGE <= 0)", so it was always false, thus radeon_atrm_get_bios() was trying to read past the bios data wasting boot time. On my lenovo ideapad u455 laptop this patch drops bios reading time from ~5.5s to ~1.5s.

If copy_from_user() does not return 0 we'll leak the memory we allocated for 'params' when that variable goes out of scope. Also a small CodingStyle cleanup: Use braces on both branches of if/else when one branch needs it.

2012-01-24ASoC: wm2000: Fix use-after-free - don't release_firmware() twice on errorJesper Juhl
In wm2000_i2c_probe(), if we take the true branch in " ret = snd_soc_register_codec(&i2c->dev, &soc_codec_dev_wm2000, NULL, 0); if (ret != 0) goto err_fw; " then we'll release_firmware(fw) at the 'err_fw' label. But we've already done that just a few lines above. That's a use-after-free bug. This patch restructures the code so that we always call release_firmware(fw) before leaving the function, but only ever call it once. This means that we have to initialize 'fw' to NULL since some paths may now end up calling it without having called request_firmware(), but since request_firmware() deals gracefully with NULL pointers, we are fine if we just NULL initialize it.

2012-01-23Use acpi_os_map_memory() instead of ioremap() in einj driverLuck, Tony
ioremap() has become more picky and is now spitting out console messages like: ioremap error for 0xbddbd000-0xbddbe000, requested 0x10, got 0x0 when loading the einj driver. What we are trying to so here is map a couple of data structures that the EINJ table points to. Perhaps acpi_os_map_memory() is a better tool for this? Most importantly it works, but as a side benefit it maps the structures into kernel virtual space so we can access them with normal C memory dereferences, so instead of using: writel(param1, &v5param->apicid); we can use the more natural: v5param->apicid = param1; Signed-off-by: Tony Luck <tony.luck@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
