Subject: [PATCH] Keys: Remove redundant initialization of cred
Date: Sat,  8 May 2021 17:51:21 +0800	[thread overview]
Message-ID: <> (raw)

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

Reported-by: Abaci Robot <>
Fixes: 'commit bb952bb98a7e ("CRED: Separate per-task-group keyrings from signal_struct")'
