From: Tomer Tayar Date: Thu, 25 Jan 2024 20:59:02 +0000 (+0200) Subject: accel/habanalabs: fix glbl error cause handling X-Git-Tag: microblaze-v6.10~28^2~19^2~9 X-Git-Url: http://git.monstr.eu/?a=commitdiff_plain;h=e855869bec3fea9f11521a21f419d5a10f4b0c12;p=linux-2.6-microblaze.git accel/habanalabs: fix glbl error cause handling The glbl error cause handling has a wrong assumption that all error bits are consecutive. Fix the handling to check all relevant error bits per ASIC.
