Hi Hannes, I love your patch! Perhaps something to improve: [auto build test WARNING on mkp-scsi/for-next] [also build test WARNING on v5.4-rc4 next-20191021] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Hannes-Reinecke/scsi-Revamp-result-values/20191022-004918 base: https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git for-next config: m68k-multi_defconfig (attached as .config) compiler: m68k-linux-gcc (GCC) 7.4.0 reproduce: wget https://raw.githubusercontent.com/intel/lkp-tests/master/sbin/make.cross -O ~/bin/make.cross chmod +x ~/bin/make.cross # save the attached .config to linux build tree GCC_VERSION=7.4.0 make.cross ARCH=m68k If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp@xxxxxxxxx> All warnings (new ones prefixed by >>): drivers/scsi/wd33c93.c: In function 'wd33c93_intr': >> drivers/scsi/wd33c93.c:1297:19: warning: passing argument 1 of 'set_host_byte' makes pointer from integer without a cast [-Wint-conversion] set_host_byte(cmd->result, DID_ERROR); ^~~ In file included from drivers/scsi/wd33c93.c:79:0: include/scsi/scsi_cmnd.h:315:20: note: expected 'struct scsi_cmnd *' but argument is of type 'int' static inline void set_host_byte(struct scsi_cmnd *cmd, char status) ^~~~~~~~~~~~~ vim +/set_host_byte +1297 drivers/scsi/wd33c93.c 1200 1201 case CSR_SDP: 1202 DB(DB_INTR, printk("SDP")) 1203 hostdata->state = S_RUNNING_LEVEL2; 1204 write_wd33c93(regs, WD_COMMAND_PHASE, 0x41); 1205 write_wd33c93_cmd(regs, WD_CMD_SEL_ATN_XFER); 1206 spin_unlock_irqrestore(&hostdata->lock, flags); 1207 break; 1208 1209 case CSR_XFER_DONE | PHS_MESS_OUT: 1210 case CSR_UNEXP | PHS_MESS_OUT: 1211 case CSR_SRV_REQ | PHS_MESS_OUT: 1212 DB(DB_INTR, printk("MSG_OUT=")) 1213 1214 /* To get here, we've probably requested MESSAGE_OUT and have 1215 * already put the correct bytes in outgoing_msg[] and filled 1216 * in outgoing_len.
