Subject: [PATCH] FBTFT: Changed delay function.
Hi,
Changed udelay() to usleep_range() based on the document in the path, "Documentation/timers/timers-howto.rst". It was suggested to use usleep_range() function for sleeping duration between 10us - 20 ms. original code used udelay() for sleeping 20 us.
