Hi All, I experienced an issue on today's next 20180514. Found on Odroid XU3 board (Exynos5422, ARMv7, octa-core) with exynos_defconfig. 1. No sound card is probed: [ 6.717698] ALSA device list: [ 6.719303] No soundcards found. (expected: #0: Odroid-XU3) 2. Oops happens: [ OK ] Started udev Kernel Device Manager. Unable to handle kernel paging request at virtual address c0f324ac [ 36.229430] [<c05764ac>] (platform_drv_probe) from [<c0573fd8>] (driver_probe_device+0x2e0/0x4b4) [ 36.238258] [<c0573fd8>] (driver_probe_device) from [<c0571fb8>] (bus_for_each_drv+0x74/0xb8) [ 36.246746] [<c0571fb8>] (bus_for_each_drv) from [<c0573bb0>] (__device_attach+0xd4/0x168) [ 36.254974] [<c0573bb0>] (__device_attach) from [<c0572e78>] (bus_probe_device+0x88/0x90) [ 36.263121] [<c0572e78>] (bus_probe_device) from [<c0573434>] (deferred_probe_work_func+0x64/0x184) [ 36.272144] [<c0573434>] (deferred_probe_work_func) from [<c0146950>] (process_one_work+0x220/0x8e8) [ 36.281236] [<c0146950>] (process_one_work) from [<c0147050>] (worker_thread+0x38/0x584) [ 36.289293] [<c0147050>] (worker_thread) from [<c014d96c>] (kthread+0x138/0x168) [ 36.296652] [<c014d96c>] (kthread) from [<c01010b4>] (ret_from_fork+0x14/0x20) 3. No DRM device is probed/found. I could not find any specific reasons of this failure (like earlier failures... except some probe deferrals which are happening almost alwats).

Hence let's respect all error codes and bail out accordingly. Signed-off-by: Ulf Hansson <ulf.hansson@xxxxxxxxxx> Acked-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> Signed-off-by: Rafael J.
