Subject: [PATCH] scatterlist: Add const to sg_set_buf/sg_init_one pointer argument
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=03fd9cee7f46dddcd2562bc175d2c348502ce281;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] scatterlist: Add const to sg_set_buf/sg_init_one pointer argument

This patch adds a const modifier to the buf argument of sg_set_buf and
sg_init_one.  This lets people call it with pointers that are const.
