Subject: SiS DRM: fix the memory allocator if the SIS FB is built as a module
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6bb9e4bff5c6fd908d907222108ef5650d77972f;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

SiS DRM: fix the memory allocator if the SIS FB is built as a module

Fix the SIS DRM memory allocator if the SIS FB built as a module.  The SIS DRM
code initialises the mm allocation hooks, but _only_ if the SIS FB is not
built as a module because it depends on CONFIG_FB_SIS, and that's unset if the
SIS FB is not built in.  It must check CONFIG_FB_SIS_MODULE as well.
