From: Michael Krufky Date: Fri, 21 Dec 2007 19:12:09 +0000 (-0300) Subject: V4L/DVB (6893): tuner-xc2028: fix xc2028_attach function X-Git-Tag: firefly_0821_release~23728^2~138 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7972f9880c8c812332a56da7cfa4523d01ea310b;p=firefly-linux-kernel-4.4.55.git V4L/DVB (6893): tuner-xc2028: fix xc2028_attach function xc2028_attach was returning an integer when disabled from the build, where it should instead be returning NULL. Declare xc2028_attach as type dvb_frontend * instead of void *. The prototype declaration must be marked as extern in the header.
