Subject: [PATCH v2 03/15] coresight: Make ETM4x TRCIDR3 register accesses consistent with sysreg.h
Date: Thu,  3 Feb 2022 12:05:51 +0000	[thread overview]
Message-ID: <20220203120604.128396-4-james.clark@arm.com> (raw)
In-Reply-To: <20220203120604.128396-1-james.clark@arm.com>

This is a no-op change for style and consistency and has no effect on the
binary produced by gcc-11.

Signed-off-by: James Clark <james.clark@arm.com>
