Subject: [PATCH v3 05/12] x86/cpu: Remove redundant comment during feature setup
Date: Fri, 9 Jun 2023 21:36:25 +0300 [thread overview]
Message-ID: <20230609183632.48706-6-alexander.shishkin@linux.intel.com> (raw)
In-Reply-To: <20230609183632.48706-1-alexander.shishkin@linux.intel.com>
From: Sohil Mehta <sohil.mehta@intel.com>
The code below the comment is self explanatory. Instead of updating the
comment with the newly added LASS feature, it is better to just remove
it.
