fbdev: omapfb: remove unused variable

2017-07-31T16:45:41+00:00

Removing the default display name left a harmless warning:

fbdev/omap2/omapfb/dss/core.c: In function 'omap_dss_probe':
fbdev/omap2/omapfb/dss/core.c:196:30: error: unused variable 'pdata' [-Werror=unused-variable]

This removes the now-unused variable as well.

omapfb: dss: Handle return errors in dss_init_ports()

2017-03-20T17:30:59+00:00

dss_init_ports() is not handling return errors from dpi_init_port() and
sdi_init_port(). It is also always returning 0 currently which results in
part of error handling code in dss_bind() being unused.

Fix dss_init_ports() to handle return errors from dpi_init_port() and
sdi_init_port().

omapfb: panel-dsi-cm: Remove deprecated create_singlethread_workqueue

2016-08-11T14:54:55+00:00

The workqueue "workqueue" has only a single workitem(&ddata->ulps_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.

dsicm_remove() calls dsicm_cancel_ulps_work which uses
cancel_delayed_work() to ensure that there are no pending tasks while
disconnecting the driver.
