Subject: ARM: l2c: omap2+: get rid of init call
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b39b14e62ac3d0a66d13123ef85aaa83fd7c90fc;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: l2c: omap2+: get rid of init call

Get rid of init call to initialize L2 cache.  Instead use the init_early
machine hook. This helps in using the initialization routine across
SoCs without the need of ugly cpu_is_*() checks.
