[PATCH 6.12.y] platform/x86: int3472: Fix uninitialised variable warning

[Sasha Levin <sashal@kernel.org>]

From: Sakari Ailus <sakari.ailus@linux.intel.com>

[ Upstream commit 70e6384fe0f4cf9768944f81924f6c1478b0ce43 ]

Fix a compiler warning about an uninitialised err_msg variable by printing
the error where it is handled:

drivers/platform/x86/intel/int3472/discrete.c:440:24: warning: ‘err_msg’ may be used uninitialized [-Wmaybe-uninitialized]
  440 |                 return dev_err_probe(int3472->dev, ret, err_msg);

Fixes: 5de691bffe57 ("platform/x86: Add intel_skl_int3472 driver")
