Subject: MIPS: Fix debugfs_create_*'s error checking method for arch/mips/math-emu/
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ecab1f4479abb88d739bc1aac5545e8399fbad66;p=openwrt%2Fstaging%2Fblogic.git

MIPS: Fix debugfs_create_*'s error checking method for arch/mips/math-emu/

debugfs_create_*() returns NULL on error.  Make its caller debugfs_fpuemu
return -ENODEV on error.
