Subject: [PATCH v1 2/2] iio: adc: ti-adc128s052: Drop anti-pattern of ACPI_PTR() use
Date: Wed, 14 Dec 2022 13:49:44 +0200	[thread overview]
Message-ID: <20221214114944.83790-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20221214114944.83790-1-andriy.shevchenko@linux.intel.com>

ACPI_PTR() is more harmful than helpful. For example, in this case
if CONFIG_ACPI=n, the ID table left unused and code is obfuscated
by ifdeffery.

Drop anti-pattern of ACPI_PTR() use.
