Subject: MIPS: Export string functions alongside their definitions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d6cb671589757ec3d20e5e0886505cdad327b1b3;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

MIPS: Export string functions alongside their definitions

Now that EXPORT_SYMBOL can be used from assembly source, move the
EXPORT_SYMBOL invocations for the strlen*, strnlen* & strncpy* functions
to be alongside their definitions.
