X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=e5719751dd41b914d52dc4870102cfc34e358571;p=linux-2.6-omap-h63xx.git

omap-keypad buildfix

Build fixes:

drivers/input/keyboard/omap-keypad.c: In function 'omap_kp_probe':
drivers/input/keyboard/omap-keypad.c:418: warning: 'row_idx' is used uninitialized in this function
drivers/input/keyboard/omap-keypad.c:421: warning: 'col_idx' is used uninitialized in this function

These variables are useful when cpu_is_omap24xx(), and otherwise just
for probe() cleanup.
