Subject: [PATCH 5.15 11/98] powerpc/prom_init: Fix kernel config grep

From: Liam Howlett <liam.howlett@...cle.com>

commit 6886da5f49e6d86aad76807a93f3eef5e4f01b10 upstream.

When searching for config options, use the KCONFIG_CONFIG shell variable
so that builds using non-standard config locations work.

Fixes: 26deb04342e3 ("powerpc: prepare string/mem functions for KASAN")
Cc: stable@...r.kernel.org # v5.2+
