Subject: goldfish bus: don't call request_mem_region
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c1bc97f8f498a2bfab63ceef761fb0e88ef7c065;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

goldfish bus: don't call request_mem_region

This is a bug fix that has been lurking in the Google tree but not pushed
upstream.

From: Octavian Purdila <octavian.purdila@intel.com>

The memory region is already reserved in goldfish_init() during
platform init.
