Subject: [POWERPC] Don't cast a struct pointer to list_head pointer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6c6199c1551b7acd4f7898f073b40ae565d3b834;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[POWERPC] Don't cast a struct pointer to list_head pointer

The casting is safe only when the list_head member is the first member
of the structure, and even then it is better to use the address of the
list_head structure member.
