[PATCH] gpio/gpiolib.c:Fixing style issues in gpiolib.c

[Mukesh Kaushik <mukesh.k4@samsung.com>]

Fixing the following checkpatch.pl error:

ERROR: else should follow close brace '}'
#2248: FILE: drivers/gpio/gpiolib.c:2248:
+       }
+       else if (test_bit(FLAG_OPEN_SOURCE, &desc->flags)) {

ERROR: space prohibited after that open parenthesis '('
#2018: FILE: drivers/gpio/gpiolib.c:2018:
+       if ( !desc->gdev->chip ) { \

ERROR: space prohibited before that close parenthesis ')'
#2018: FILE: drivers/gpio/gpiolib.c:2018:
+       if ( !desc->gdev->chip ) { \

and following warnings :

WARNING: Prefer 'unsigned int' to bare use of 'unsigned'

WARNING: else is not generally useful after a break or return
#160: FILE: drivers/gpio/gpiolib.c:160:
+                       break;
+               else
