Subject: [ARM] mmp: fix for variables in uncompress.h being discarded
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7471f46d74e0e2a668f4bc085ef486b1079b3466;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[ARM] mmp: fix for variables in uncompress.h being discarded

Due to commit:

    5de813b  ARM: Eliminate decompressor -Dstatic= PIC hack

The data section will be discarded for the decompressor, thus move the
static variables into BSS section by initializing them at run time.
