Subject: [PATCH v3] MIPS: Remove repetitive increase irq_err_count

From: huhai <[email protected]>

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.

This is missing your the Signed-off-by as submitter of the patch.

Crap can work. Given enough thrust pigs will fly, but it's not necessarily a
good idea. [ RFC1925, 2.3 ]
