Subject: [RFC PATCH v6 08/32] x86/apic: Remove redundant parentheses around 'bitmap'
Date: Wed, 14 May 2025 12:47:39 +0530 [thread overview]
Message-ID: <20250514071803.209166-9-Neeraj.Upadhyay@amd.com> (raw)
In-Reply-To: <20250514071803.209166-1-Neeraj.Upadhyay@amd.com>
When doing pointer arithmetic in apic_{clear|set|test}_vector(),
remove the unnecessary parentheses surrounding the 'bitmap'
parameter.
No functional changes intended.
