[PATCH] staging: fbtft: fb_watterott: fix usleep_range is preferred over udelay

Fix the checkpath.pl issue on fb_watterott.c. write_vmem and write_vmem_8bit functions are within non-atomic context and can safely use usleep_range. see Documentation/timers/timers-howto.txt Signed-off-by: Hassan Shahbazi --- drivers/staging/fbtft/fb_watterott.c | 4 ++-- 1 file changed, 2
