Subject: [PATCH] ASoC: txx9: don't work around too small resource_size_t
Git-commit: acfaaf52ebfd02de509bc212fc3e8c8bac187110
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518
The txx9 sound driver deends on HAS_TXX9_ACLC, which is only set for
three tx49xx SOCs, and thus always has a 64-bit phys_addr_t and
resource_size_t. Instead of poking into ioremap internals to work
around a potentially too small resource_size_t just add a BUILD_BUG_ON
to catch such a case.
