Reading it again, I do have some more comments, actually. > Could I get a review for the rest of the set? > There will actually be quite a few more patches that follow these. I think that is part of the problem. What you want to achieve is all good, but something else is not quite right. Reading through these patches felt like a lot of work, although it should not really be that much. A closer look suggests the patches are on average 20% too large, the rest being irrelevant changes. That may look small, but apparently it is off-putting enough. The less work it is to accept your patches, the more likely they are to be processed quickly. Please find brief notes below. > > Daniel Kurtz (14): > > =A0Input: atmel_mxt_ts - use CONFIG_PM_SLEEP Seems to clash with current mainline. > > =A0Input: atmel_mxt_ts - only allow root to update firmware OK. > > =A0Input: atmel_mxt_ts - refactor mxt_read/write_reg to take a leng= th The return value change should be split out in a separate patch, subject to stable as well. Also, there is no real benefit in changing the name from __mxt to mxt. It only makes the patch longer. > > =A0Input: atmel_mxt_ts - verify object size in mxt_write_object OK, also stable material. > > =A0Input: atmel_mxt_ts - do not read extra (checksum) byte OK. > > =A0Input: atmel_mxt_ts - dump each message on just 1 line OK. > > =A0Input: atmel_mxt_ts - refactor mxt_object_show Start of for loop does not need to change. The buf_end - buf is less clear than the existing PAGE_SIZE - count. The realloc feels clunky, could it not allocate the max size once instead? > > =A0Input: atmel_mxt_ts - optimize writing of object table entries Seems the index variable could be kept, no real need to move the bject deklaration around, small things like that. > > =A0Input: atmel_mxt_ts - refactor get info Why not keep mxt_get_info(), just using the smaller implementation?
