a=openpgp; fpr=9BD07E0E0C51F8D59677B7541B93437D3B41629B RFT/RFC because testing needed. I tried to do the same on exynos5-subcmu and it caused weird oopses which even KASAN did not narrow. Probably because of multiple exynos5-subcmu devices? Switch registering platform driver to platform_driver_probe(), so the 'struct platform_driver' can be properly discarded after init and there won't be need of __refdata to silence DEBUG_SECTION_MISMATCH. The change requires using subsys_initcall instead of core_initcall, because no device drivers would bound in the latter, as required by platform_driver_probe().
