Regression : Latitude 5500 do not always go to true sleep mode

by Léo COLISSON

Dear Linux maintainers, Since I upgraded my system (from NixOs release 2caf4ef5005ecc68141ecb4aac271079f7371c44, running linux 5.15.90, to b8697e57f10292a6165a20f03d2f42920dfaf973, running linux 6.6.19), my system started to experience a weird behavior : when closing the lid, the system does not always go to a true sleep mode : when I restart it, the battery is drained. Not sure what I can try here. You can find more information on my tries here, with some journalctl logs : - https://github.com/NixOS/nixpkgs/issues/299464 - https://discourse.nixos.org/t/since-upgrade-my-laptop-does-not-go-to-sleep-… Cheers, Léo

[PATCH] drm/i915/display: fix display param dup for NULL char * params

by Jani Nikula

The display param duplication deviates from the original param duplication in that it converts NULL params to to allocated empty strings. This works for the vbt_firmware parameter, but not for dmc_firmware_path, the user of which interprets NULL and the empty string as distinct values. Specifically, the empty dmc_firmware_path leads to DMC and PM being disabled. Just remove the NULL check and pass it to kstrdup(), which safely returns NULL for NULL input. Fixes: 8015bee0bfec ("drm/i915/display: Add framework to add parameters specific to display") Fixes: 0d82a0d6f556 ("drm/i915/display: move dmc_firmware_path to display params") Cc: Jouni Högander <jouni.hogander(a)intel.com> Cc: Luca Coelho <luciano.coelho(a)intel.com> Cc: <stable(a)vger.kernel.org> # v6.8+ Signed-off-by: Jani Nikula <jani.nikula(a)intel.com> --- drivers/gpu/drm/i915/display/intel_display_params.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/i915/display/intel_display_params.c b/drivers/gpu/drm/i915/display/intel_display_params.c index c8e3d6892e23..49c6b42077dc 100644 --- a/drivers/gpu/drm/i915/display/intel_display_params.c +++ b/drivers/gpu/drm/i915/display/intel_display_params.c @@ -176,9 +176,9 @@ void intel_display_params_dump(struct drm_i915_private *i915, struct drm_printer #undef PRINT } -__maybe_unused static void _param_dup_charp(char **valp) +static void _param_dup_charp(char **valp) { - *valp = kstrdup(*valp ? *valp : "", GFP_ATOMIC); + *valp = kstrdup(*valp, GFP_ATOMIC); } __maybe_unused static void _param_nop(void *valp) -- 2.39.2
