Subject: cxl: remove redundant increment of hwirq
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d3383aaae9800b9e13e25b71f70dff3814d10373;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

cxl: remove redundant increment of hwirq

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.
