Moikka Thomas,

Here is the review. See comments below.

And conclusion is that it is ready for the Kernel merge. I did not see
any big functiuonality problems - only some small issues that are likely
considered as a coding style etc. Feel free to fix those and sent new
patc serie or just new patch top of that.

Use one space around (on each side of) most binary and ternary operators,
such as any of these:

          =  +  -<    >    *  /  %  |&    ^<=>=  ==  !=  ?  :

Bitshift operators seems to be OK.
Something else?

(len-1-i)*8
I almost have a new corrected version of the patch series ready, fixing this issues and the
other ones you mentioned.

- 1 indication apropos 'media/dvb/frontends/rtl2832_priv.h:30'
Compared to 'rtl2830_priv.h' seems to be OK.

./checkpatch.pl --no-tree
v4-1-5-rtl2832-ver.-0.4-removed-signal-statistics.patch.orig
ERROR: Missing Signed-off-by: line(s)

total: 1 errors, 0 warnings, 1177 lines checked

v4-1-5-rtl2832-ver.-0.4-removed-signal-statistics.patch.orig has style
problems, please review.  If any of these errors
are false positives report them to the maintainer, see
CHECKPATCH in MAINTAINERS.

How do you produce this error:
"ERROR: Macros with complex values should be enclosed in parenthesis…"?

Just running checkpatch.pl --file foo


For me checkpath.pl also does not report the error you reported. It does seem
strange to me, as the makros are the same as in rtl2830_priv.h

Are you using some old version of checkpatch.pl ?
Mine is:
commit c06a9ebdb7a4f4823d4225fe789d8c20a1d534eb
Author: Joe Perches <joe@xxxxxxxxxxx>
Date:   Mon Apr 16 13:35:11 2012 -0600

If you are using older version then upgrade. checkpatch.pl is developed very rapidly and there is all the time new checks.

regards
Antti
