Subject: i3c: dw: make resets optional in probe
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=f077a6b07be1939eb5865fb6afe60ed3c545edb0;p=thirdparty%2Fu-boot.git

i3c: dw: make resets optional in probe

Treat -ENOENT and -ENOTSUPP from reset_get_bulk() as non-fatal to
support platforms where no resets are defined in the DTS. The resets
property is not yet documented in the DT binding.
