fbdev: ffb: fix corrupted video output on Sun FFB1

2026-03-04T12:21:43+00:00

[ Upstream commit b28da0d092461ac239ff034a8ac3129320177ba3 ] Fix Sun FFB1 corrupted video out ([1] and [2]) by disabling overlay and initializing window mode to a known state. The issue never appeared on my FFB2+/vertical nor Elite3D/M6. It could also depend on the PROM version. /SUNW,ffb@1e,0: FFB at 000001fc00000000, type 11, DAC pnum[236c] rev[10] manuf_rev[4] X (II) /dev/fb0: Detected FFB1, Z-buffer, Single-buffered.

fbdev: of: display_timing: fix refcount leak in of_get_display_timings()

2026-03-04T12:21:42+00:00

[ Upstream commit eacf9840ae1285a1ef47eb0ce16d786e542bd4d7 ] of_parse_phandle() returns a device_node with refcount incremented, which is stored in 'entry' and then copied to 'native_mode'. When the error paths at lines 184 or 192 jump to 'entryfail', native_mode's refcount is not decremented, causing a refcount leak. Fix this by changing the goto target from 'entryfail' to 'timingfail', which properly calls of_node_put(native_mode) before cleanup.

fbcon: check return value of con2fb_acquire_newinfo()

[ Upstream commit 011a0502801c8536f64141a2b61362c14f456544 ] If fbcon_open() fails when called from con2fb_acquire_newinfo() then info->fbcon_par pointer remains NULL which is later dereferenced. Add check for return value of the function con2fb_acquire_newinfo() to avoid it. Found by Linux Verification Center (linuxtesting.org) with SVACE.

fbdev: Use device_create_with_groups() to fix sysfs groups registration race

2026-03-04T12:21:42+00:00

[ Upstream commit 68eeb0871e986ae5462439dae881e3a27bcef85f ] The fbdev sysfs attributes are registered after sending the uevent for the device creation, leaving a race window where e.g. udev rules may not be able to access the sysfs attributes because the registration is not done yet. Fix this by switching to device_create_with_groups(). This also results in a nice cleanup. After switching to device_create_with_groups() all that is left of fb_init_device() is setting the drvdata and that can be passed to device_create[_with_groups]() too. After which fb_init_device() can be completely removed. Dropping fb_init_device() + fb_cleanup_device() in turn allows removing fb_info.class_flag as they were the only user of this field.
