Subject: [media] m88ds3103: One function call less in m88ds3103_init() after error detection
X-Git-Tag: android-x86-4.4-r3~477^2~101
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=5ed0cf8800c4da58e1e501f7143154897d34e9c2;p=android-x86%2Fkernel.git

[media] m88ds3103: One function call less in m88ds3103_init() after error detection

GIT_AUTHOR_DATE=1416472158
The release_firmware() function was called in some cases by the
m88ds3103_init() function during error handling even if the passed variable
contained still a null pointer. This implementation detail could be improved
by the introduction of another jump label.
