Hi Kiran, Thank you for the patch! Perhaps something to improve: [auto build test WARNING on bluetooth-next/master] [also build test WARNING on next-20200611] [cannot apply to bluetooth/master v5.7] [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/Kiran-K/Add-support-for-new-gene... base: https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git master config: powerpc-randconfig-s031-20200611 (attached as .config) compiler: powerpc64le-linux-gcc (GCC) 9.3.0 reproduce: # apt-get install sparse # sparse version: v0.6.1-250-g42323db3-dirty # save the attached .config to linux build tree make W=1 C=1 ARCH=powerpc CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' If you fix the issue, kindly add following tag as appropriate Reported-by: kernel test robot <lkp(a)intel.com&gt; sparse warnings: (new ones prefixed by >>) drivers/bluetooth/btintel.c:427:26: sparse: sparse: cast to restricted __le16 drivers/bluetooth/btintel.c:428:26: sparse: sparse: cast to restricted __le16 drivers/bluetooth/btintel.c:429:26: sparse: sparse: cast to restricted __le16 vim +418 drivers/bluetooth/btintel.c 384 385 bool btintel_get_fw_name(struct intel_version *ver, 386 struct intel_boot_params *params, 387 char *fw_name, size_t len, 388 const char *suffix) 389 { 390 /* This is for legacy HCI_Intel_Read_Version command. 391 * 392 * With this Intel bootloader only the hardware variant and device 393 * revision information are used to select the right firmware for SfP 394 * and WsP. 395 * 396 * The firmware filename is ibt-<hw_variant>-<dev_revid>.sfi. 397 * 398 * Currently the supported hardware variants are: 399 * 11 (0x0b) for iBT3.0 (LnP/SfP) 400 * 12 (0x0c) for iBT3.5 (WsP) 401 * 402 * For ThP/JfP and for future SKU's, the FW name varies based on HW 403 * variant, HW revision and FW revision, as these are dependent on CNVi 404 * and RF Combination. 405 * 406 * 17 (0x11) for iBT3.5 (JfP) 407 * 18 (0x12) for iBT3.5 (ThP) 408 * 409 * The firmware file name for these will be 410 * ibt-<hw_variant>-<hw_revision>-<fw_revision>.sfi. 411 * 412 */ 413 414 switch (ver->hw_variant) { 415 case 0x0b: /* SfP */ 416 case 0x0c: /* WsP */ 417 snprintf(fw_name, len, "intel/ibt-%u-%u.%s", 419 le16_to_cpu(params->dev_revid), 420 suffix); 421 break; 422 case 0x11: /* JfP */ 423 case 0x12: /* ThP */ 424 case 0x13: /* HrP */ 425 case 0x14: /* CcP */ 426 snprintf(fw_name, len, "intel/ibt-%u-%u-%u.%s", 427 le16_to_cpu(ver->hw_variant), 428 le16_to_cpu(ver->hw_revision), 429 le16_to_cpu(ver->fw_revision), 430 suffix); 431 break; 432 default: 433 return false; 434 } 435 return true; 436 } 437 EXPORT_SYMBOL_GPL(btintel_get_fw_name); 438 --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org
