Subject: [PATCH] i3c: dw: make struct dw_i3c_cmd smaller
Date: Thu, 13 Aug 2026 12:46:03 +0800 [thread overview]
Message-ID: <20260813044603.22425-1-jszhang@kernel.org> (raw)
The dw_i3c_cmd is dynamically allocated, make it smaller. For example
on 64bit platforms, we reduce the size from 48 bytes to 32 bytes.
