Subject: hdlc: Remove typedefs from struct names
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3fadb06daef958d2ae2d3be363a0cfaa92008b52;p=openwrt%2Fstaging%2Fblogic.git

hdlc: Remove typedefs from struct names

The Linux kernel coding style guidelines suggest not using typedefs
for structure types. This patch gets rid of the typedefs for
fr_hdr and pvc_device. Also, the names of the structs are changed to
drop the _t, to make the name look less typedef-like.

The following Coccinelle semantic patch detects the case fr_hdr and a
similar one detects the case for pvc_device.

typedef struct { ... } td;
