Hi Andy, I love your patch! Yet something to improve: [auto build test ERROR on pinctrl/devel] [also build test ERROR on v5.8-rc1 next-20200615] [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/Andy-Shevchenko/pinctrl-intel-Re... base: https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git devel config: x86_64-rhel-7.6 (attached as .config) compiler: gcc-9 (Debian 9.3.0-13) 9.3.0 reproduce (this is a W=1 build): # save the attached .config to linux build tree make W=1 ARCH=x86_64 If you fix the issue, kindly add following tag as appropriate Reported-by: kernel test robot <lkp(a)intel.com&gt; All errors (new ones prefixed by >>, old ones prefixed by <<): drivers/pinctrl/intel/pinctrl-intel.c: In function 'intel_restore_hostown': 1601 | for_each_requested_gpio_in_range(&pctrl->chip, i, padgrp->gpio_base, padgrp->size, dummy) | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1601 | for_each_requested_gpio_in_range(&pctrl->chip, i, padgrp->gpio_base, padgrp->size, dummy) | ^ | ; 1602 | requested |= BIT(i); | ~~~~~~~~~ cc1: some warnings being treated as errors vim +/for_each_requested_gpio_in_range +1601 drivers/pinctrl/intel/pinctrl-intel.c 1587 1588 static void intel_restore_hostown(struct intel_pinctrl *pctrl, unsigned int c, 1589 void __iomem *base, unsigned int gpp, u32 saved) 1590 { 1591 const struct intel_community *community = &pctrl->communities[c]; 1592 const struct intel_padgroup *padgrp = &community->gpps[gpp]; 1593 struct device *dev = pctrl->dev; 1594 const char *dummy; 1595 u32 requested = 0; 1596 unsigned int i; 1597 1598 if (padgrp->gpio_base == INTEL_GPIO_BASE_NOMAP) 1599 return; 1600 1602 requested |= BIT(i); 1603 1604 if (!intel_gpio_update_reg(base + gpp * 4, requested, saved)) 1605 return; 1606 1607 dev_dbg(dev, "restored hostown %u/%u %#08x\n", c, gpp, readl(base + gpp * 4)); 1608 } 1609 --- 0-DAY CI Kernel Test Service, Intel Corporation https://lists.01.org/hyperkitty/list/kbuild-all@lists.01.org
