Alexey thank you very much for your review, hints and most of all patience ;) The code really gets cleaner and cleaner. While changing the code (once again ;) and looking at your remarks I also saw that ab3550->debug_address and ->debug_bank are always casted to u8. Do you think I could also change the two fields of the struct ab3550 (only used in this file) to u8 in this patch, too? This way I could get rid of the u8* cast which is now needed in this case, if I take you last remark into account. > err = kstrtou8_from_user(user_buf, count, 0, (u8 *)&ab->debug_address); And also clean the code from all the other unnecessary u8 casts. What do you think? Or split it up into two seperate patches?
