Subject: [PATCH v3 2/2] aspeed/sdmc: Remove extra R_MAIN_STATUS case
Date: Tue, 25 Jun 2024 15:07:40 +0800	[thread overview]
Message-ID: <20240625070741.2852946-3-jamin_lin@aspeedtech.com> (raw)
In-Reply-To: <20240625070741.2852946-1-jamin_lin@aspeedtech.com>

Coverity reports that the newly added 'case R_MAIN_STATUS' is DEADCODE
because it can not be reached. This is because R_MAIN_STATUS is handled
before in the "Unprotected registers" switch statement. Remove it.

Fixes: Coverity CID 1547112
