Subject: [PATCH 2/6] Fix dangerous relocation
Without this fix the linker complains:
WARNING: EXPORT symbol "gsi_write_channel_scratch" [vmlinux] version generation failed, symbol will not be versioned.
aarch64-linux-gnu-ld: warning: -z norelro ignored
aarch64-linux-gnu-ld: drivers/platform/msm/gsi/gsi.o: relocation R_AARCH64_ABS32 against `__crc_gsi_write_channel_scratch' can not be used when making a shared object
drivers/platform/msm/gsi/gsi.o:(.data+0x0): dangerous relocation: unsupported relocation
drivers/platform/msm/gsi/gsi.o:(.data+0x28): dangerous relocation: unsupported relocation
drivers/platform/msm/gsi/gsi.o:(.data+0x50): dangerous relocation: unsupported relocation
make[1]: *** [/home/iskren/src/pmos/android_kernel_samsung_msm8974/Makefile:1124: vmlinux] Error 1
The problem is actually that genksyms doesn't understand __packed in
function return type.
