From ea63a8990151948b87dfc0502028bcc7d6724dbc Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Thu, 9 Dec 2021 16:59:37 +0200 Subject: ata: libahci_platform: Remove bogus 32-bit DMA mask attempt 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").
