    checkpatch: fix handling of leading spaces · 5f7ddae6
    Raffaele Recalcati authored
    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.
