Subject: [PATCH] serial: 8250_dw: Drop wrong use of ACPI_PTR()
Git-commit: ebabb77a2a115b6c5e68f7364b598310b5f61fb2
Patch-mainline: v5.16-rc1
References: git-fixes stable-5.14.19

ACPI_PTR() is more harmful than helpful. For example, in this case
if CONFIG_ACPI=n, the ID table left unused which is not what we want.

Instead of adding ifdeffery here and there, drop ACPI_PTR().
