Subject: ppp: fix build with kernel 4.14.9+
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=04cb1e0fd20196e2e6ec5f8864f5d694f134cbc1;p=openwrt%2Fstaging%2Fneocturne.git

ppp: fix build with kernel 4.14.9+

With a9772285a724 ("linux/compiler.h: Split into compiler.h and
compiler_types.h") compiler.h was refactored and most its content was
moved to compiler_types.h. Both files are required to build ppp-mod-pppoa.
