Subject: [PATCH 2/8] Input: cap11xx - remove unused register macros
Date: Sat,  6 Jun 2026 23:03:55 +0800	[thread overview]
Message-ID: <20260606150458.250606-3-jerrysteve1101@gmail.com> (raw)
In-Reply-To: <20260606150458.250606-1-jerrysteve1101@gmail.com>

Remove unused register address macros and unused definitions in
the cap11xx_reg_defaults array and cap11xx_volatile_reg.

This cleanup reduces code clutter and makes the driver easier to
maintain without affecting functionality.
