Subject: [PATCH] [media] mt9v032: Add missing initialization of pdata in mt9v032_get_pdata()

drivers/media/i2c/mt9v032.c: In function ‘mt9v032_get_pdata’:
drivers/media/i2c/mt9v032.c:885: warning: ‘pdata’ may be used uninitialized in this function

If parsing the endpoint node properties fails, mt9v032_get_pdata() will
return an uninitialized pointer value.
