From: Tejun Heo Date: Fri, 29 Aug 2008 14:27:43 +0000 (+0200) Subject: libata-sff: kill spurious WARN_ON() in ata_hsm_move() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9c2676b61a5a4b6d99e65fb2f438fb3914302eda;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git libata-sff: kill spurious WARN_ON() in ata_hsm_move() On HSM_ST_ERR, ata_hsm_move() triggers WARN_ON() if AC_ERR_DEV or AC_ERR_HSM is not set. PHY events may trigger HSM_ST_ERR with other error codes and, with or without it, there just isn't much reason to do WARN_ON() on it. Even if error code is not set there, core EH logic won't have any problem dealing with the error condition. OSDL bz#11065 reports this problem.
