From a0e881e2c5739145a54561751c3c43f07e44d462 Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 10 Jun 2019 20:10:54 +0300 Subject: [PATCH] gpio: omap: simplify bank->level_mask bank->level_mask is merely the bitwise or of the level detection context which we have already read in this function. Rather than repeating additional reads, compute it from the values already read.
