From: Jon Hunter Date: Wed, 1 Apr 2026 13:34:41 +0000 (+0100) Subject: gpiolib: Make deferral warnings debug messages X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=779ae2232cd1fd80661327e503606df004b4cda4;p=thirdparty%2Fkernel%2Flinux.git gpiolib: Make deferral warnings debug messages With the recent addition of the shared GPIO support, warning messages such as the following are being observed ... reg-fixed-voltage regulator-vdd-3v3-pcie: cannot find GPIO chip gpiolib_shared.proxy.6, deferring These are seen even with GPIO_SHARED_PROXY=y. Given that the GPIOs are successfully found a bit later during boot and the code is intentionally returning -EPROBE_DEFER when they are not found, downgrade these messages to debug prints to avoid unnecessary warnings being observed. Note that although the 'cannot find GPIO line' warning has not been observed in this case, it seems reasonable to make this print a debug print for consistency too.
