[ Upstream commit a58c22cfbbf62fefca090334bbd35fd132e92a23 ]

The device_node pointer is returned by of_parse_phandle()  with refcount
incremented. We should use of_node_put() on it when done.

video: omapfb: replace snprintf in show functions with sysfs_emit

2021-10-15T20:52:10+00:00

coccicheck complains about the use of snprintf() in sysfs show functions.

Fix the coccicheck warning:
WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.

fbdev/omap2: use DEFINE_SPINLOCK() instead of spin_lock_init().

2021-06-17T17:43:42+00:00

spinlock can be initialized automatically with DEFINE_SPINLOCK()
rather than explicitly calling spin_lock_init().

fbdev: omapfb: avoid -Wempty-body warning

2021-03-22T14:02:14+00:00

Building with 'make W=1' shows a few harmless warnings:

drivers/video/fbdev/omap2/omapfb/omapfb-main.c: In function 'omapfb_calc_addr':
drivers/video/fbdev/omap2/omapfb/omapfb-main.c:823:56: error: suggest braces around empty body in an 'if' statement [-Werror=empty-body]

      |                                                        ^
drivers/video/fbdev/omap2/omapfb/omapfb-ioctl.c: In function 'omapfb_ioctl':

  911 |                 DBG("ioctl failed: %d\n", r);

Avoid these by using no_printk(), which adds format string checking as
well.

video: omapfb: Remove WARN_ON(in_interrupt()).

2021-02-18T14:14:32+00:00

dsi_sync_vc() uses in_interrupt() to create a warning if the function is
used in non-preemptible context.

The usage of in_interrupt() in drivers is phased out and Linus clearly
requested that code which changes behaviour depending on context should
either be separated or the context be conveyed in an argument passed by the
caller, which usually knows the context.

The wait_for_completion() function (used in dsi_sync_vc_vp() and
dsi_sync_vc_l4() has already a check if it is invoked from proper
context.

Remove WARN_ON(in_interrupt()) from the driver.
