Subject: module: return error when mod_sysfs_init() failed
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d58ae67813ff97030d2f47ff7d1e5f54e5d7c5b3;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

module: return error when mod_sysfs_init() failed

load_module() returns zero when mod_sysfs_init() fails, then the module
loading will succeed accidentally.

This patch makes load_module() return error correctly in that case.
