2017-02-28ALSA: ctxfi: Fallback DMA mask to 32bitTakashi Iwai
Currently ctxfi driver tries to set only the 64bit DMA mask on 64bit architectures, and bails out if it fails. This causes a problem on some platforms since the 64bit DMA isn't always guaranteed. We should fall back to the default 32bit DMA when 64bit DMA fails. Fixes: 6d74b86d3c0f ("ALSA: ctxfi - Allow 64bit DMA") Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2017-02-28drm: qxl: Consolidate bo reservation when pinningGabriel Krisman Bertazi
Every attempt to pin/unpin objects in memory requires qxl_bo_reserve/unreserve calls around the pinning operation to protect the object from concurrent access, which causes that call sequence to be reproduced every place where pinning is needed. In some cases, that sequence was not executed correctly, resulting in potential unprotected pinning operations. This commit encapsulates the reservation inside a new wrapper to make sure it is always handled properly. In cases where reservation must be done beforehand, for some reason, one can use the unprotected version __qxl_bo_pin/unpin.

2017-02-28drm: Rename connector list iterator APIThierry Reding
Currently the functions that initialize and tear down a connector iterator use the _get() and _put() suffixes. However, these suffixes are typically used by reference counting functions. Make these function names a little more consistent by changing the suffixes to _begin() and _end(), which is a fairly common pattern in the rest of the Linux kernel.

2017-02-28drm: Rename drm_mode_object_get()Thierry Reding
Subsequent patches will introduce reference counting APIs that are more consistent with similar APIs throughout the Linux kernel. These APIs use the _get() and _put() suffixes and will collide with this existing function. Rename the function to drm_mode_object_add() which is a slightly more accurate description of what it does. Also the kerneldoc for this function gives an indication that it's badly named because it doesn't actually acquire a reference to anything.

2017-02-28ALSA: timer: Reject user params with too small ticksTakashi Iwai
When a user sets a too small ticks with a fine-grained timer like hrtimer, the kernel tries to fire up the timer irq too frequently. This may lead to the condensed locks, eventually the kernel spinlock lockup with warnings. For avoiding such a situation, we define a lower limit of the resolution, namely 1ms. When the user passes a too small tick value that results in less than that, the kernel returns -EINVAL now.
