[PATCH 1/4] crypto: omap-sham: Remove useless check for non-null request

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



ahash_request 'req' argument passed by the caller
omap_sham_handle_queue() cannot be NULL here because it is obtained from
non-NULL pointer via container_of().

This fixes smatch warning:
    drivers/crypto/omap-sham.c:812 omap_sham_prepare_request() warn: variable dereferenced before check 'req' (see line 805)
