Subject: crypto: omap-aes - fix the reference count leak of omap device
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=383e8a823014532ffd81c787ef9009f1c2bd3b79;p=linux.git

crypto: omap-aes - fix the reference count leak of omap device

pm_runtime_get_sync() will increment  pm usage counter even
when it returns an error code. We should call put operation
in error handling paths of omap_aes_hw_init.
