Subject: [PATCH v2 08/15] coresight: Make ETM4x TRCSTALLCTLR register accesses consistent with sysreg.h
Date: Thu, 3 Feb 2022 12:05:56 +0000 [thread overview]
Message-ID: <20220203120604.128396-9-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>
