From 29171dcfaa639921954c8b2cd1b7de59888a1081 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Thu, 21 Sep 2017 16:51:36 +0200 Subject: [PATCH] mmc: omap_hsmmc: Fix incorrect bit operations for disabling a bit omap_hsmmc driver uses "|" in a couple of places for disabling a bit. While it's okay to use it in "mmc_reg_out" (since mmc_reg_out has a _mask_ argument to take care of resetting a bit), it's incorrectly used for resetting flags in "omap_hsmmc_send_cmd". Fix it here by using "&= ~()" to reset a bit.
