X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cf7125ae05e5ac671eec2508656816bbc0a8c723;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ide: fix handling of busy I/O resources in probe_hwif()

It could be that I/O resources are busy because some other host driver
has already claimed them so don't unregister the devices.
