      video: bfin_adv7393fb: Convert to kstrtouint_from_user · 5c888aa4
      由 Emil Goode 提交于 
      This patch removes a call to the deprecated simple_strtoul function
and simplifies the code by replacing two function calls with one
call to kstrtouint_from_user.

-Simplify the adv7393_write_proc function by replacing the
 simple_strtoul and copy_from_user calls with one call
 to kstrtouint_from_user.

-Change the count parameter from unsigned long to size_t as
 this is the type that the kstrtouint_from_user function expects.
 (size_t is what will be passed to the adv7393_write_proc function
 by the proc write handler function proc_file_write anyway)

      OMAPDSS: DSI: Fix bug when calculating LP command interleaving parameters · 2e063c30
      由 Archit Taneja 提交于 
      In function dsi_compute_interleave_lp(), the escape clock/LP clock time period
is calculated incorrectly. The escape clock/LP clock is calculated as:

LP Clock(Hz) = DSI_FCLK(Hz) / lp_clk_div

Since we are calculating the time period of LP clock, the LP clock divider
should be multiplied with the time period of DSI_FCLK.

Calculating incorrect value of txclkesc results in incorrect calculation of LP
interleaving parameters, it also creates a possibility of a divide by zero
error.

      OMAPDSS: fix bogus WARN_ON in dss_runtime_put() · 5025ce07
      由 Tomi Valkeinen 提交于 
      pm_runtime_put_sync() in dss_runtime_put() returns -EBUSY when any child
of dss is still enabled. This happens, for example, when a display
output is enabled and one dumps the clocks via debugfs. This causes
dss_runtime_get & put to be called.

While I couldn't find anything about this in the documentation and it
wasn't immediately clear from runtime_pm code, it looks to me that
pm_runtime_put_sync() returns -EBUSY to inform that things went fine,
but the device could not be turned off as there are still child devices
that are enabled. This is not a problem.

This patch skips the WARN_ON if pm_runtime_put_sync() returns -EBUSY.

      OMAPDSS: fix build when DEBUG_FS or DSS_DEBUG_SUPPORT disabled · 0e9a126e
      由 Tomi Valkeinen 提交于 
      If CONFIG_DEBUG_FS or CONFIG_OMAP2_DSS_DEBUG_SUPPORT is disabled, the
build fails:

drivers/video/omap2/dss/core.c:197:50: error: static declaration of
'dss_debugfs_create_file' follows non-static declaration
drivers/video/omap2/dss/dss.h:166:5: note: previous declaration of
'dss_debugfs_create_file' was here

This patch fixes the dummy dss_debugfs_create_file() so that the driver
builds.
