Subject: [PATCH 01/12] hw_random: mxc-rngc: fix read of uninitialized variable
Date: Wed, 30 Sep 2020 09:19:54 +0200 [thread overview]
Message-ID: <20200930072005.1407-1-a.fatoum@pengutronix.de> (raw)
err is evaluated in a ternary condition on return, but if the while
loop is never entered, it is left uninitialized. Fix this.
Reported-by: clang-analyzer-10
