[PATCH] cxl: remove redundant increment of hwirq

From: Colin King
Date: Thu Jan 08 2015 - 17:37:55 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

hwirq has not been initialized, however it is being incremented
and also not being referenced in a loop. This error was detected with
cppcheck:

[drivers/misc/cxl/irq.c:439]: (error) Uninitialized variable: hwirq

Commit 80fa93fce37d ("cxl: Name interrupts in /proc/interrupt")
introduced this error.

This is a simple fix that removes the redundant increment.
