Subject: [PATCH 01/15] wifi: iwlwifi: fix EWRD table validity check
Date: Mon, 29 Jan 2024 21:21:49 +0200 [thread overview]
Message-ID: <20240129211905.448ea2f40814.Iffd2aadf8e8693e6cb599bee0406a800a0c1e081@changeid> (raw)
In-Reply-To: <20240129192203.4189915-1-miriam.rachel.korenblit@intel.com>
EWRD ACPI table contains up to 3 additional sar profiles.
According to the BIOS spec, the table contains a n_profile
variable indicating how many additional profiles exist in the
table.
Currently we check that n_profiles is not <= 0.
But according to the BIOS spec, 0 is a valid value,
and it can't be < 0 anyway because we receive that from ACPI as
an unsigned integer.
Fixes: 39c1a9728f93 ("iwlwifi: refactor the SAR tables from mvm to acpi")
