Subject: crypto: omap-des - fix error return code in omap_des_probe()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=59af156625ab1d11436b04806ee3c1c795b29a93;p=linux-beck.git

crypto: omap-des - fix error return code in omap_des_probe()

Fix to return error code -ENOMEM from the crypto_engine_alloc_init()
error handling case instead of 0, as done elsewhere in this function.

Fixes: f1b77aaca85a ("crypto: omap-des - Integrate with the crypto
engine framework")
