Thanks for the patch but it is already fixed by Dmitry as below.

An "if" testing for error condition has accidentally been dropped from the code.
		error = device_property_read_string(dev, gpi_str3, &str);
+		if (!error)
 			haptics->gpi_ctl[i].polarity =
 				da7280_haptic_of_gpi_pol_str(dev, str);

Kind regards,
Roy

Huh...  Well, at least the kbuild bot discovered this using the Smatch
warning for inconsistent indenting so that's nice.

https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org/thread/IB3H2KDL2HZ5WGNAER7TLCJQHZJH7S7E/

This is one of the first real bugs that that indenting has found, maybe
if Smatch had used some more of the context clues the warning could have
been made better.

Presumably W=1 and some of the other analysis tools would have warned
about the unused "error = " assignment if we had waited another day.
