Subject: Blackfin: sram_free_with_lsl: do not ignore return value of sram_free
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25f3ff2c445822793d22ac51e3dcb22a694e3cd4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Blackfin: sram_free_with_lsl: do not ignore return value of sram_free

If there was an error in the lower free functions, we need to pass that
back up so the calling process is able to check things.
