Subject: ARM: l2c: remove unnecessary call to outer_flush_all()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b13b9e98b80fa24460a011ba0378d3fe56137a31;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

ARM: l2c: remove unnecessary call to outer_flush_all()

outer_disable() is defined to safely turn the L2 cache off without data
loss: this means that outer_flush_all() should never be called unless
you need to implement some special L2 cache disabling, and even then
only from your replacement L2 cache disable function.
