Subject: net: cdc_ncm: Export cdc_ncm_{tx, rx}_fixup functions for re-use
X-Git-Tag: v3.13-rc1~105^2~53^2~2
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2f69702c4db5f1c3149fd17fe30bdeb87cba9698;p=karo-tx-linux.git

net: cdc_ncm: Export cdc_ncm_{tx, rx}_fixup functions for re-use

Some drivers implementing NCM-like protocols, may re-use those functions, as is
the case in the huawei_cdc_ncm driver.
Export them via EXPORT_SYMBOL_GPL, in accordance with how other functions have
been exported.
