[LEDE-DEV] [PATCH 0/2] procd: dev_exist() refactoring

[Jo-Philipp Wich]

Refactor the dev_exist() function of inittab.c to use openat() instead of the
race condition prone chdir()/open()/chdir() sequence.

The refactoring allows us to drop the now unused dev_open(), so kill it.
While we touch openat() things, also change patch_fd() of utils.c to use
stricter flags when opening the "/dev" directory.

Jo-Philipp Wich (2):
  inittab: use more robust dev_exist() implementation
  utils: use O_PATH when opening /dev
