[PATCH] Keys: Remove redundant initialization of cred

From: Yang Li
Date: Sat May 08 2021 - 05:51:34 EST


Pointer cred is being initialized however this value is never
read as cred is assigned an updated value from the returned
call to get_current_cred(). Remove the redundant initialization.

Cleans up clang warning:

security/keys/request_key.c:119:21: warning: Value stored to 'cred'
during its initialization is never read
[clang-analyzer-deadcode.DeadStores]
