Subject: mmc: Register debugfs dir before calling card probe function.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1a2727e98786136fb968b18d96f8ecdd9ba38aa8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mmc: Register debugfs dir before calling card probe function.

This way, the probe function may register debugfs files if it wants to.
This fixes a bug with mmc_test where mmc_test_register_file_test() is
called before the card's debugfs dir exists, and so it fails.
