Subject: [PATCH] ata: ahci: use correct macro when calculating offsets in dma memory
Date: Thu, 5 May 2022 17:44:40 +0300 [thread overview]
Message-ID: <20220505144440.29188-1-denorl2009@gmail.com> (raw)
The macro that indicates the size of a single element in the command
list was incorrectly used instead of the macro that stands for the size
of the whole list.
