It looks like there are 4 uses in -next

drivers/staging/mt7621-mmc/dbg.h:110:            host->id,  ##args , __FUNCTION__, __LINE__, current->comm, current->pid);      \
drivers/staging/mt7621-mmc/dbg.h:118:          host->id,  ##args, __FUNCTION__, __LINE__, current->comm, current->pid); \
drivers/staging/mt7621-mmc/dbg.h:129:          host->id,  ##args, __FUNCTION__, __LINE__, current->comm, current->pid); \
drivers/staging/mt7621-mmc/dbg.h:136:          host->id,  ##args, __FUNCTION__, __LINE__);      \

If you are going to fix this by substitution,
please fix all of them, even if commented out.

And likely, all these uses should all be converted
to dev_<level> instead without __func__ or __LINE__
or current->comm and current->pid.

And relatedly, these are single statement macros and
don't need do while (0);

And the ; after while (0) is unnecessary.
