Subject: module: fix linker error for MODULE_VERSION when !MODULE and CONFIG_SYSFS=n
X-Git-Tag: firefly_0821_release~7613^2~2607^2~2
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3b90a5b292321b2acac3921f77046ae195aef53f;p=firefly-linux-kernel-4.4.55.git

module: fix linker error for MODULE_VERSION when !MODULE and CONFIG_SYSFS=n

lib/built-in.o:(__modver+0x8): undefined reference to `__modver_version_show'
lib/built-in.o:(__modver+0x2c): undefined reference to `__modver_version_show'

Simplest to just not emit anything: if they've disabled SYSFS they probably
want the smallest kernel possible.
