Merge tag 'fbdev-v4.19' of https://github.com/bzolnier/linux
Pull fbdev updates from Bartlomiej Zolnierkiewicz: "Mostly small fixes and cleanups for fb drivers (the biggest updates are for udlfb and pxafb drivers). This also adds deferred console takeover support to the console code and efifb driver. Summary: - add support for deferred console takeover, when enabled defers fbcon taking over the console from the dummy console until the first text is displayed on the console - together with the "quiet" kernel commandline option this allows fbcon to still be used together with a smooth graphical bootup (Hans de Goede) - improve console locking debugging code (Thomas Zimmermann) - copy the ACPI BGRT boot graphics to the framebuffer when deferred console takeover support is used in efifb driver (Hans de Goede) - update udlfb driver - fix lost console when the user unplugs a USB adapter, fix the screen corruption issue, fix locking and add some performance optimizations (Mikulas Patocka) - update pxafb driver - fix using uninitialized memory, switch to devm_* API, handle initialization errors and add support for lcd-supply regulator (Daniel Mack) - add support for boards booted with a DeviceTree in pxa3xx_gcu driver (Daniel Mack) - rename omap2 module to omap2fb.ko to avoid conflicts with omap1 driver (Arnd Bergmann) - enable ACPI-based enumeration for goldfishfb driver (Yu Ning) - fix goldfishfb driver to make user space Android code use 60 fps (Christoffer Dall) - print big fat warning when nomodeset kernel parameter is used in vgacon driver (Lyude Paul) - remove VLA usage from fsl-diu-fb driver (Kees Cook) - misc fixes (Julia Lawall, Geert Uytterhoeven, Fredrik Noring, Yisheng Xie, Dan Carpenter, Daniel Vetter, Anton Vasilyev, Randy Dunlap, Gustavo A. R. Silva, Colin Ian King, Fengguang Wu) - misc cleanups (Roman Kiryanov, Yisheng Xie, Colin Ian King)" * tag 'fbdev-v4.19' of https://github.com/bzolnier/linux: (54 commits) Documentation/fb: corrections for fbcon.txt fbcon: Do not takeover the console from atomic context dummycon: Stop exporting dummycon_[un]register_output_notifier fbcon: Only defer console takeover if the current console driver is the dummycon fbcon: Only allow FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER if fbdev is builtin fbdev: omap2: omapfb: fix ifnullfree.cocci warnings fbdev: omap2: omapfb: fix bugon.cocci warnings fbdev: omap2: omapfb: fix boolreturn.cocci warnings fb: amifb: fix build warnings when not builtin fbdev/core: Disable console-lock warnings when fb.lockless_register_fb is set console: Replace #if 0 with atomic var 'ignore_console_lock_warning' udlfb: use spin_lock_irq instead of spin_lock_irqsave udlfb: avoid prefetch udlfb: optimization - test the backing buffer udlfb: allow reallocating the framebuffer udlfb: set line_length in dlfb_ops_set_par udlfb: handle allocation failure udlfb: set optimal write delay udlfb: make a local copy of fb_ops udlfb: don't switch if we are switching to the same videomode ...
