From: Arnd Bergmann Date: Mon, 30 Sep 2019 12:14:33 +0000 (+0200) Subject: crypto: inside-secure - Fix a maybe-uninitialized warning X-Git-Tag: v5.5-rc1~175^2~214 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=74e6bd472b6d9e80ec9972989d8991736fe46c51;p=linux.git crypto: inside-secure - Fix a maybe-uninitialized warning A previous fixup avoided an unused variable warning but replaced it with a slightly scarier warning: drivers/crypto/inside-secure/safexcel.c:1100:6: error: variable 'irq' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] This is harmless as it is impossible to get into this case, but the compiler has no way of knowing that. Add an explicit error handling case to make it obvious to both compilers and humans reading the source.
