Subject: [PATCH] powerpc: Fix ide-pmac sysfs entry
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=22192ccd6d1dfea2a41e40442997ccad5b7b160e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] powerpc: Fix ide-pmac sysfs entry

It looks like the generic ide code now wants ide_init_hwif_ports() to set
the parent struct device into the ide_hw structure (new field ?).  Without
this, the mac ide code can cause the ide probing code to explode in flames
in sysfs registration due to what looks like a stale pointer in there
(happens when removing/re-inserting one of the hotswap media bays on some
laptops).
