fbdev: omapfb: delete check_required_callbacks()

2017-04-14T11:38:32+00:00

Commit 561eb9d09a93 ("fbdev: omap/lcd: Make callbacks optional") made panel callbacks optional but forgot to update check_required_callbacks(). As a result many (all?) OMAP systems using omapfb will crash at boot. Fix by deleting the whole function.

fbdev: omap/lcd: Make callbacks optional

2017-01-30T16:39:49+00:00

Most OMAP FB LCD drivers don't have anything to do in their panel callbacks. This leads to a large set of empty boilerplate functions in the panel drivers. Make those callbacks optional by checking if they are set before calling them. This allows those boilerplate functions to be removed.

fbdev: omap/lcd: Staticize non-exported lcd_panel structs

2017-01-30T16:39:49+00:00

None of the lcd_panel structs defined by the OMAP LCD drivers are referenced outside of their compilation unit. Follow best practices and mark them as static. Cc: Tomi Valkeinen Signed-off-by: Lars-Peter Clausen Signed-off-by: Bartlomiej Zolnierkiewicz

fbdev: omap/lcd: Remove no-op driver callbacks

2017-01-30T16:39:49+00:00

Every single one of the OMAP fbdev LCD drivers implements no-op remove, suspend and resume callbacks for their platform_driver. This is not necessary as the driver core handles the case where the callbacks are not set just fine. So they are just unnecessary boilerplate that can be removed.

fbdev: Remove deprecated create_singlethread_workqueue

2016-08-11T14:54:56+00:00

The workqueue "esd_wq" has only a single workitem(&md->esd_work) and hence doesn't require ordering. Also, it is not being used on a memory reclaim path. Hence, the singlethreaded workqueue has been replaced with the use of system_wq. System workqueues have been able to handle high level of concurrency for a long time now and hence it's not required to have a singlethreaded workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue created with create_singlethread_workqueue(), system_wq allows multiple work items to overlap executions even on the same CPU; however, a per-cpu workqueue doesn't have any CPU locality or global ordering guarantee unless the target CPU is explicitly specified and thus the increase of local concurrency shouldn't make any difference. mipid_esd_stop_check () calls cancel_delayed_work() in mipid_cleanup() to ensure that there are no pending tasks while disconnecting the driver.
