From: Wu Zhangjin Date: Thu, 2 Jul 2009 15:23:03 +0000 (+0800) Subject: MIPS: Loongson: clean up the coding style X-Git-Tag: firefly_0821_release~12938^2~30 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=5e983ff654ca3df3007b5b558b5271bb4622afa4;p=firefly-linux-kernel-4.4.55.git MIPS: Loongson: clean up the coding style With the help of script/checkpatch.pl, i have cleaned up the coding style. 1. remove un-needed header files and tune some comments. 2. remove some un-needed { } add a new header file loongson.h: 3. move some common header files to loongson.h 4. move some common extern declartions to loongson.h and this new header file is needed for future loongson2f support.
