[PATCH 6.8 306/399] fbdev: Select I/O-memory framebuffer ops for SBus

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.8-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Zimmermann <tzimmermann@xxxxxxx>

commit a8eb93b42d7e068306ca07f51055cbcde893fea3 upstream.

Framebuffer I/O on the Sparc Sbus requires read/write helpers for
I/O memory. Select FB_IOMEM_FOPS accordingly.
