Subject: i2c: designware_i2c: Don't warn if reset DT property is not present
X-Git-Tag: v2025.10~12
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=522a58af836598918758b41b110a73f35b9335ba;p=thirdparty%2Fu-boot.git

i2c: designware_i2c: Don't warn if reset DT property is not present

If reset property is missing in DT, then we get this warning:
	designware_i2c@0: Can't get reset: -2

Avoid this by checking if reset DT property is present, first.
