Subject: msm: show_resume_irq: print the irq name
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=de3078c3bf35e61500b0ae7cc272eb94e3a27498;p=sagit-ice-cold%2Fkernel_xiaomi_msm8998.git

msm: show_resume_irq: print the irq name

Just printing the irq number is not informative. Update the code
to show the name of the interrupt's irq action.
