Merge tag 'fbdev-v4.15' of git://github.com/bzolnier/linux

Pull fbdev updates from Bartlomiej Zolnierkiewicz:
"There is nothing really major here (though removal of the dead igafb
driver stands out in diffstat).

Summary:

- convert timers to use timer_setup() (Kees Cook, Thierry Reding)

- fix panels support on iMX boards in mxsfb driver (Stefan Agner)

- fix timeout on EDID read in udlfb driver (Ladislav Michl)

- add missing modes to fix out of bounds access in controlfb driver
(Geert Uytterhoeven)

- update initialisation paths in sa1100fb driver to be more robust
(Russell King)

- fix error handling path of ->probe method in au1200fb driver
(Christophe JAILLET)

- fix handling of cases when either panel or crt is defined in
sm501fb driver (Sudip Mukherjee, Colin Ian King)

- add ability to the Goldfish FB driver to be recognized by OS via DT
(Aleksandar Markovic)

- structures constifications (Bhumika Goyal)

- misc fixes (Allen Pais, Gustavo A. R. Silva, Dan Carpenter)

- misc cleanups (Colin Ian King, Himanshu Jha, Markus Elfring)

- remove dead igafb driver"
