checkpatch: fix handling of leading spaces
I've got a false positive when spaces are present at the beginning of a line. So I add this check, obviously excluding to check the lines in the middle of comments. For instance this code passes the checkpatch test: +struct davinci_mcbsp_data { + unsigned int fmt; + int clk_div; +}; + +static struct davinci_mcbsp_data mcbsp_data; Where, before the string "int clk_div", I have 4 spaces (\040 ascii character). With v2.6.34 scripts/checkpatch.pl script I get: scripts/checkpatch.pl 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch total: 0 errors, 0 warnings, 201 lines checked 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch has no obvious style problems and is ready for submission. That is not correct. Instead with the proposed patch I get: scripts/checkpatch.pl 0001-ASoC-DaVinci-Added-support-for-stereo-I2S.patch WARNING: please, no space for starting a line, excluding comments #63: FILE: sound/soc/davinci/davinci-i2s.c:165: + int clk_div;$ WARNING: please, no space for starting a line, excluding comments #95: FILE: sound/soc/davinci/davinci-i2s.c:406: + return 0;$ total: 0 errors, 2 warnings, 201 lines checked That is correct.
