[PATCH 1/1] dm: pinctrl: include linux/errno.h in pinctrl.h

[Sébastien Szymanski]

Otherwise the compilation fails with PINCTRL_GENERIC=n :

In file included from drivers/pinctrl/nxp/pinctrl-imx8m.c:7:0:
include/dm/pinctrl.h: In function ‘pinctrl_generic_set_state’:
include/dm/pinctrl.h:319:10: error: ‘EINVAL’ undeclared (first use in this function)
  return -EINVAL;
          ^~~~~~
include/dm/pinctrl.h:319:10: note: each undeclared identifier is reported only once for each function it appears in
