drm/imagination: Fix missing argument in pvr_power_fw_{en,dis}able()

2026-05-20T08:52:10+00:00

Commit 42577ba79fbf ("drm/imagination: Rename FW booted to FW initialised") dropped by mistake the last argument of the functions pvr_power_fw_enable() and pvr_power_fw_disable(), leading to the following compile error: CC [M] drivers/gpu/drm/imagination/pvr_power.o drivers/gpu/drm/imagination/pvr_power.c: In function ‘pvr_power_device_suspend’: drivers/gpu/drm/imagination/pvr_power.c:382:23: error: too few arguments to function ‘pvr_power_fw_disable’; expected 3, have 2 382 | err = pvr_power_fw_disable(pvr_dev, false); | ^~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/imagination/pvr_power.c:93:1: note: declared here 93 | pvr_power_fw_disable(struct pvr_device *pvr_dev, bool hard_reset, bool rpm_suspend) | ^~~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/imagination/pvr_power.c: In function ‘pvr_power_device_resume’: drivers/gpu/drm/imagination/pvr_power.c:412:23: error: too few arguments to function ‘pvr_power_fw_enable’; expected 2, have 1 412 | err = pvr_power_fw_enable(pvr_dev); | ^~~~~~~~~~~~~~~~~~~ drivers/gpu/drm/imagination/pvr_power.c:122:1: note: declared here 122 | pvr_power_fw_enable(struct pvr_device *pvr_dev, bool rpm_resume) | ^~~~~~~~~~~~~~~~~~~ make[6]: *** [scripts/Makefile.build:289: drivers/gpu/drm/imagination/pvr_power.o] Error 1 make[5]: *** [scripts/Makefile.build:548: drivers/gpu/drm/imagination] Error 2 make[4]: *** [scripts/Makefile.build:548: drivers/gpu/drm] Error 2 make[3]: *** [scripts/Makefile.build:548: drivers/gpu] Error 2 make[2]: *** [scripts/Makefile.build:548: drivers] Error 2 make[1]: *** [/home/javier/devel/linux/Makefile:2141: .] Error 2 make: *** [Makefile:248: __sub-make] Error 2 Fixes: 42577ba79fbf ("drm/imagination: Rename FW booted to FW initialised") Reviewed-by: Brajesh Gupta Link: https://patch.msgid.link/20260519131239.1291732-1-javierm@redhat.com Signed-off-by: Javier Martinez Canillas
