I did not build this change by the time I sent you this, thinking this is just a style change. I should have tested the build. I am sorry. Now I built the changes by setting the following configurations. CONFIG_GREYBUS CONFIG_STAGING CONFIG_GREYBUS_LOOPBACK My change introduces the following error. '''' drivers/staging/greybus/loopback.c:166:2: error: expected identifier or ‘(’ before ‘do’ 166 | do { \ | ^~ '''' I could not fix or find the reason for this error. Please guide me in this regard. Thanks, Husni.
