X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1fdc90fb8fb752d4d8d2602115cf4bd071374068;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git mmc: omap_hsmmc: Handle failure of regulator_get better. 1/ If regulator_get fails, return an error. This is important if it failed with EPROBE_DEFER, as the probe needs to be deferred. 2/ Don't set .set_power until the regulator has been found, or the deferred probe will not bother calling omap_hsmmc_reg_get().
