X-Git-Tag: v3.4-rc1~177^2~108^2~156
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=549040abbc03e87bdee2964fea5e4c827471d4df;p=platform%2Fkernel%2Flinux-3.10.git

brcm80211: fmac: initialize host interface drivers regardless result

The module init function of brcmfmac calls init functions for SDIO and
USB doing driver registration. This patch removes terminating the module
init when a driver registration for one host interface fails.
