Subject: checkpatch: fix handling of leading spaces
From: Raffaele Recalcati <raffaele.recalcati@xxxxxxxxxx>
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.
