Subject: [PATCH v1 2/2] ata: libahci_platform: Remove bogus 32-bit DMA mask attempt
Date: Thu, 9 Dec 2021 16:59:37 +0200 [thread overview]
Message-ID: <20211209145937.77719-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20211209145937.77719-1-andriy.shevchenko@linux.intel.com>
If 64-bit mask attempt fails, the 32-bit will fail by the very same reason.
Don't even try the latter. It's a continuation of the changes that contains,
e.g. dcc02c19cc06 ("sata_sil24: use dma_set_mask_and_coherent").
