[PATCH] dmaengine: ppc4xx: fix format specifiers for size_t arguments

From: Rosen Penev

Date: Thu Sep 10 2026 - 17:21:12 EST


Several dev_err, dev_dbg, pr_debug, and printk calls use %d or %u
format specifiers for size_t arguments (len, pool_size). Fix them
to use %zu to avoid warnings on 64-bit builds.

Fixes: 12458ea06efd7 ("ppc440spe-adma: adds updated ppc440spe adma driver")
