From f6ca57e4f40528a8a0103c9f0e9647a2e11d10c3 Mon Sep 17 00:00:00 2001 From: Adrian Schmutzler Date: Fri, 9 Oct 2020 16:44:30 +0200 Subject: oxnas: fix qc_prep return in sata driver after kernel 5.4.69 This fixes a regression after a kernel change in 5.4.69 [1] that led to build failure on oxnas/ox820: drivers/ata/sata_oxnas.c:2238:13: error: initialization of 'enum ata_completion_errors (*)(struct ata_queued_cmd *)' from incompatible pointer type 'void (*)(struct ata_queued_cmd *)' [-Werror=incompatible-pointer-types] .qc_prep = sata_oxnas_qc_prep, ^~~~~~~~~~~~~~~~~~ drivers/ata/sata_oxnas.c:2238:13: note: (near initialization for 'sata_oxnas_ops.qc_prep') Our local driver is changed the same way as prototyped in the kernel patch, i.e. return type is changed and AC_ERR_OK return value is added.
