[PATCH v4 3/7] fbdev: au1100fb: Use proper conversion specifiers in printk formats

STALE230d

From: Uwe Kleine-König <hidden>
Date: 2026-02-15 13:59:04
Also in: dri-devel
Subsystem: framebuffer layer, the rest · Maintainers: Helge Deller, Linus Torvalds

%zu is the dedicated type for size_t. %d only works on 32bit
architectures where size_t is typedef'd to be unsigned int. (And then
the signedness doesn't fit, but `gcc -Wformat` doesn't stumble over this.
Also the size of dma_addr_t is architecture dependant and it should be
printkd using %pad (and the value passed by reference).

This prepares allowing this driver to be compiled on non-mips platforms.
