[PATCH 4.19 16/49] MIPS: Remove repetitive increase irq_err_count

[Greg Kroah-Hartman]

From: huhai <huhai@xxxxxxxxxx>

[ Upstream commit c81aba8fde2aee4f5778ebab3a1d51bd2ef48e4c ]

commit 979934da9e7a ("[PATCH] mips: update IRQ handling for vr41xx") added
a function irq_dispatch, and it'll increase irq_err_count when the get_irq
callback returns a negative value, but increase irq_err_count in get_irq
was not removed.

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

So it would be a good idea to remove repetitive increase irq_err_count in
get_irq callback.

Fixes: 27fdd325dace ("MIPS: Update VR41xx GPIO driver to use gpiolib")
Fixes: 979934da9e7a ("[PATCH] mips: update IRQ handling for vr41xx")
