Subject: [PATCH -next 1/2] video: fbdev: pxa168fb: Remove unnecessary print function dev_err()

The print function dev_err() is redundant because platform_get_irq()
already prints an error.

Eliminate the follow coccicheck warning:
./drivers/video/fbdev/pxa168fb.c:621:2-9: line 621 is redundant because
platform_get_irq() already prints an error

Please drop the surrounding braces then as well in both of your patches, e.g.

if (irq < 0)
return -ENOENT;
