Subject: ft1000-pcmcia: ft1000_hw.c: code refactoring: add ft1000_read_dsp_timer()
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=de5160ffd279dc6e7fa070a4a3852c6c5be42f9c;p=openwrt%2Fstaging%2Fblogic.git

ft1000-pcmcia: ft1000_hw.c: code refactoring: add ft1000_read_dsp_timer()

Add new function ft1000_read_dsp_timer() replacing recurring code block for
reading DSP timer. Such code refactoring solves all remaining "line over 80
characters" warnings reported by checkpatch.pl.
