Hi Abhishek, Thank you for the patch! Yet something to improve: [auto build test ERROR on bluetooth-next/master] [cannot apply to v5.4-rc7 next-20191112] [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/Abhishek-Pandit-Subedi/Bluetooth... base: https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git master config: sparc64-allmodconfig (attached as .config) compiler: sparc64-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=sparc64 If you fix the issue, kindly add following tag Reported-by: kbuild test robot <lkp(a)intel.com&gt; All errors (new ones prefixed by >>): drivers/bluetooth/hci_bcm.c: In function 'bcm_setup': err = btbcm_set_pcm_params(hu->hdev, &bcm->dev->pcm_params, ^~~~~~~~~~~~~~~~~~~~ btbcm_set_pcm_int_params cc1: some warnings being treated as errors vim +606 drivers/bluetooth/hci_bcm.c 543 544 static int bcm_setup(struct hci_uart *hu) 545 { 546 struct bcm_data *bcm = hu->priv; 547 char fw_name[64]; 548 const struct firmware *fw; 549 unsigned int speed; 550 int err; 551 552 bt_dev_dbg(hu->hdev, "hu %p", hu); 553 554 hu->hdev->set_diag = bcm_set_diag; 555 hu->hdev->set_bdaddr = btbcm_set_bdaddr; 556 557 err = btbcm_initialize(hu->hdev, fw_name, sizeof(fw_name), false); 558 if (err) 559 return err; 560 561 err = request_firmware(&fw, fw_name, &hu->hdev->dev); 562 if (err < 0) { 563 bt_dev_info(hu->hdev, "BCM: Patch %s not found", fw_name); 564 return 0; 565 } 566 567 err = btbcm_patchram(hu->hdev, fw); 568 if (err) { 569 bt_dev_info(hu->hdev, "BCM: Patch failed (%d)", err); 570 goto finalize; 571 } 572 573 /* If we disallow early set baudrate, we can re-enable it now that 574 * patchram is done 575 */ 576 if (bcm->dev && bcm->dev->disallow_set_baudrate) 577 bcm->dev->disallow_set_baudrate = false; 578 579 /* Init speed if any */ 580 if (hu->init_speed) 581 speed = hu->init_speed; 582 else if (hu->proto->init_speed) 583 speed = hu->proto->init_speed; 584 else 585 speed = 0; 586 587 if (speed) 588 host_set_baudrate(hu, speed); 589 590 /* Operational speed if any */ 591 if (hu->oper_speed) 592 speed = hu->oper_speed; 593 else if (hu->proto->oper_speed) 594 speed = hu->proto->oper_speed; 595 else 596 speed = 0; 597 598 if (speed) { 599 err = bcm_set_baudrate(hu, speed); 600 if (!err) 601 host_set_baudrate(hu, speed); 602 } 603 604 /* PCM parameters if any*/ 605 if (bcm->dev && bcm->dev->has_pcm_params) { 607 NULL); 608 609 if (err) { 610 bt_dev_info(hu->hdev, "BCM: Set pcm params failed (%d)", 611 err); 612 } 613 } 614 615 finalize: 616 release_firmware(fw); 617 618 err = btbcm_finalize(hu->hdev); 619 if (err) 620 return err; 621 622 if (!bcm_request_irq(bcm)) 623 err = bcm_setup_sleep(hu); 624 625 return err; 626 } 627 --- 0-DAY kernel test infrastructure Open Source Technology Center https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org Intel Corporation
