From 982192e2a1b3152d4ccc4483d1967d3ca672ad7d Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 3 May 2021 20:21:13 +0300 Subject: staging: fbtft: Replace custom ->reset() with generic one The custom ->reset() repeats the generic one, replace it. Note, in newer kernels the context of the function is a sleeping one, it's fine to switch over to the sleeping functions. Keeping the reset line asserted longer than 20 microseconds is also okay, it's an idling state of the hardware.
