Subject: ipw2200: return error code on error in ipw_wx_get_auth()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8df0f1e5cbd4ff1e2059a1e11bd89b35aa5ed004;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

ipw2200: return error code on error in ipw_wx_get_auth()

We have assinged error code to 'ret' when get auth from some
option is not supported but never used it, but we'd better return
the error code.
