From f5abd8a616d1e8d9ff6c1fbd5d10496ab5dcf1ea Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Mon, 4 Jan 2021 08:02:52 +0100 Subject: [PATCH] ram: k3-j721e: rename BIT_MASK() The macro BIT_MASK is already defined in include/linux/bitops.h. To avoid name collisions rename BIT_MASK() in drivers/ram/k3-j721e/lpddr4_private.h to LPDDR4_BIT_MASK(). Remove superfluous parantheses. Remove superfluous comparison to 0.
