Subject: devpts: simplify two-level sysctl registration for pty_kern_table
X-Git-Tag: v6.4-rc1~192^2~11
X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=3e27877ac565807135209933e0894d8c522cc520;p=linux-2.6-block.git

devpts: simplify two-level sysctl registration for pty_kern_table

There is no need to declare two tables to just create directories,
this can be easily be done with a prefix path with register_sysctl().

Simplify this registration.
