commit 864eb1afc60cb43e7df879b97f8ca0d719bbb735 upstream.

Clang warns when multiple pairs of parentheses are used for a single
conditional statement.

drivers/video/fbdev/sis/init301.c:851:42: warning: equality comparison
with extraneous parentheses [-Wparentheses-equality]
      } else if((SiS_Pr->SiS_IF_DEF_LVDS == 1) /* ||
                 ~~~~~~~~~~~~~~~~~~~~~~~~^~~~
drivers/video/fbdev/sis/init301.c:851:42: note: remove extraneous
parentheses around the comparison to silence this warning
      } else if((SiS_Pr->SiS_IF_DEF_LVDS == 1) /* ||
                ~                        ^   ~
drivers/video/fbdev/sis/init301.c:851:42: note: use '=' to turn this
equality comparison into an assignment
      } else if((SiS_Pr->SiS_IF_DEF_LVDS == 1) /* ||
                                         ^~
                                         =
1 warning generated.

Remove the parentheses and while we're at it, clean up the commented
code, which has been here since the beginning of git history.

commit 32ad61951574d011d363694d6037592e99da9421 upstream.

The variables modeflag and resinfo were only assigned some value but
were never used.

Delete successive assignments to the same location.  The second assignment
is changed to update a different field, as done in other nearby code.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@@
expression i;
@@

*i = ...;
 i = ...;
// </smpl>

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.

Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.

No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.
