Subject: serial: xuartps: Remove __init marking from early write
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=99d2731678723b86a7fe17319214fdbe53e4fc0c;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

serial: xuartps: Remove __init marking from early write

The earlycon would be alive outside the init code in these cases:
1/ we have keep_bootcon in cmdline.
2/ we don't have a real console to switch to.

So remove the __init marking to avoid invalid memory access.
