Subject: [PATCH] irq: mips: Export irq_err_count to modules

From: huhai <huhai@...inos.cn>

modpost complains once these drivers become modules.
  ERROR: modpost: "irq_err_count" [drivers/gpio/gpio-vr41xx.ko] undefined!

Fix it by export them when that symbol is =m.

Fixes: 27fdd325dace ("MIPS: Update VR41xx GPIO driver to use gpiolib")
