Subject: efivarfs: Use sizeof() instead of magic number
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=94a193fb7393a50625abd9ca21f8afea275a9f87;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

efivarfs: Use sizeof() instead of magic number

Instead of adding a magic 4 to the variable size, use sizeof() to make
it explicitly clear what the quantity represents (the variable's
attributes).
