From 815b6cb37e8e9c4da06e7a52d7215a6dc1965e02 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Thu, 2 Dec 2021 15:27:08 +0900 Subject: ata: ahci_ceva: Fix id array access in ceva_ahci_read_id() ATA IDENTIFY command returns an array of le16 words. Accessing it as a u16 array triggers the following sparse warning: drivers/ata/ahci_ceva.c:107:33: warning: invalid assignment: &= drivers/ata/ahci_ceva.c:107:33: left side has type unsigned short drivers/ata/ahci_ceva.c:107:33: right side has type restricted __le16 Use a local variable to explicitly cast the id array to __le16 to avoid this warning.
