[PATCH] PM / devfreq: rockchip: add PM_DEVFREQ_EVENT dependency

[PATCH] PM / devfreq: rockchip: add PM_DEVFREQ_EVENT dependency

[Arnd Bergmann]

The newly added ARM_RK3399_DMC_DEVFREQ driver requires the
DEVFREQ_EVENT_ROCKCHIP_DFI driver and tries to turn that on through
a 'select' statement, and that in turn has a dependency on
PM_DEVFREQ_EVENT, which may be disabled here:

warning: (ARM_RK3399_DMC_DEVFREQ) selects DEVFREQ_EVENT_ROCKCHIP_DFI which has unmet direct dependencies (PM_DEVFREQ && PM_DEVFREQ_EVENT && ARCH_ROCKCHIP)

We probably want a 'depends on' here, but other drivers use 'select'
too, so for consistency I'm doing the same.

Thank you.

Being tested at: https://git.kernel.org/cgit/linux/kernel/git/mzx/devfreq.git/log/?h=for-4.9-rc


@ The branch above requires additional patches to be tested
(other rockchip support drivers to be merged for 4.9 and COMPILE_TEST retraction for TEGRA)
