Subject: [MIPS] Remove support for sysmips(2) SETNAME and MIPS_RDNVRAM operations.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=235a9d3eee9a9588c17d39efff8373d0513549b5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

[MIPS] Remove support for sysmips(2) SETNAME and MIPS_RDNVRAM operations.

SETNAME only had a minor defect but probably never had a user and
MIPS_RDNVRAM was unimplemented anyway.
