Subject: IB/ocrdma: fix bad initialization
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5b4c9cd7e4790f37b595aeb4bf6fcbf7e3ba9e2c;p=linux-beck.git

IB/ocrdma: fix bad initialization

In function ocrdma_mbx_create_ah_tbl(), returns the value of status on
errors. However, because status is initialized with 0, 0 will be
returned even if on error paths. This patch initialize status with
"-ENOMEM".
