2011-11-04hwmon: Use i2c_smbus_{read,write}_word_swappedJean Delvare19-234/+115
Make use of the new i2c_smbus_{read,write}_word_swapped functions. This makes the driver code more compact and readable. It also ensures proper error handling.

2011-11-04hwmon: (lm90) Make code more readableJean Delvare1-74/+69
Clean up the code to make it more readable: * Remove reg_ and new_ prefixes from variable names, they made the names longer, causing extra line breaks, while not adding much value. * Introduce struct device dev* = &client->dev in two functions, to avoid repeating client->dev everywhere in these functions.

2011-11-04hwmon: (lm90) Fix warningsJean Delvare1-15/+16
With some configuration option combinations, we get the following warnings: drivers/hwmon/lm90.c: In function 'lm90_detect': drivers/hwmon/lm90.c:1114: warning: 'chip_id' may be used uninitialized in this function drivers/hwmon/lm90.c:1114: warning: 'reg_config1' may be used uninitialized in this function drivers/hwmon/lm90.c:1114: warning: 'reg_convrate' may be used uninitialized in this function drivers/hwmon/lm90.c:1187: warning: 'reg_emerg2' may be used uninitialized in this function drivers/hwmon/lm90.c:1187: warning: 'reg_status2' may be used uninitialized in this function We can solve these easily by reading the register values first and checking for errors later. These errors should be very rare, even in the case of failed detection, so this change has no impact on performance. And this makes checkpatch.pl happier.

2011-11-04drm/radeon/kms: consolidate GART code, fix segfault after GPU lockup V2Jerome Glisse10-116/+75
After GPU lockup VRAM gart table is unpinned and thus its pointer becomes unvalid. This patch move the unpin code to a common helper function and set pointer to NULL so that page update code can check if it should update GPU page table or not.

2011-11-04target: Add generic active I/O shutdown logicNicholas Bellinger1-5/+127
This patch adds the initial pieces of generic active I/O shutdown logic. This is intended to be a 'opt-in' feature for fabric modules that includes the following functions to provide a mechinism for fabric modules to track se_cmd via se_session->sess_cmd_list: *) target_get_sess_cmd() - Add se_cmd to sess->sess_cmd_list, called from fabric module incoming I/O path. *) target_put_sess_cmd() - Check for completion or drop se_cmd from ->sess_cmd_list *) target_splice_sess_cmd_list() - Splice active I/O list from ->sess_cmd_list to ->sess_wait_list, can called with HW fabric lock held. *) target_wait_for_sess_cmds() - Walk ->sess_wait_list waiting on individual ->cmd_wait_comp. Optional transport_wait_for_tasks() call. target_splice_sess_cmd_list() is allowed to be called under HW fabric lock, and performs the splice into se_sess->sess_wait_list and set se_cmd->cmd_wait_set. Then target_wait_for_sess_cmds() walks the list waiting for individual target_put_sess_cmd() fabric callbacks to complete. It also adds TFO->check_release_cmd() to split the completion and memory release calls, where a fabric module uses target_put_sess_cmd() to check for I/O completion during session shutdown. This is currently pushed out into fabric modules as current fabric code may sleep here waiting for TFO->check_stop_free() to complete in main response path, and because target_wait_for_sess_cmds() calling TFO->release_cmd() to free fabric descriptor memory directly.

2011-11-03[media] V4L: soc-camera: make (almost) all client drivers re-usable outside ↵Guennadi Liakhovetski4-27/+65
of the framework The most important change in this patch is direct linking to struct soc_camera_link via the client->dev.platform_data pointer. This makes most of the soc-camera client drivers also usable outside of the soc-camera framework. After this change all what is needed for these drivers to function are inclusions of soc-camera headers for some convenience macros, suitably configured platform data, which is anyway always required, and loaded soc-camera core module for library functions. If desired, these library functions can be made generic in the future and moved to a more neutral location. The only two client drivers, that still depend on soc-camera are: mt9t031: it uses struct video_device for its PM. Since no hardware is available, alternative methods cannot be tested. ov6650: it uses struct soc_camera_device to pass its sense data back to the bridge driver. A generic v4l2-subdevice approach should be developed to perform this. Signed-off-by: Guennadi Liakhovetski <[email protected]> Signed-off-by: Mauro Carvalho Chehab <[email protected]>
