X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3b88508a31a77eb3487154922e1eff282dc1d863;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git [S390] cio: no path after machine check. Devices enter no-path state after disabling a channel path via the SE even though another path has been reenabled at the SE. The devices are set into no-path state before triggering path verification even though other paths may have become available. To fix this trigger path verification before setting a device into no-path state.
