PM / devfreq: exynos-ppmu: Fix excessive stack usage
[ Upstream commit d4556f5e99d5f603913bac01adaff8670cb2d08b ]
Putting a 'struct devfreq_event_dev' object on the stack is generally
a bad idea and here it leads to a warnig about potential stack overflow:
drivers/devfreq/event/exynos-ppmu.c:643:12: error: stack frame size of 1040 bytes in function 'exynos_ppmu_probe' [-Werror,-Wframe-larger-than=]
There is no real need for the device structure, only the string inside
it, so add an internal helper function that simply takes the string
as its argument and remove the device structure.
