Petersen" <martin.petersen@...cle.com>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 5.10 040/171] scsi: pm8001: Fix pm80xx_pci_mem_copy() interface From: Damien Le Moal <damien.lemoal@...nsource.wdc.com> [ Upstream commit 3762d8f6edcdb03994c919f9487fd6d336c06561 ] The declaration of the local variable destination1 in pm80xx_pci_mem_copy() as a pointer to a u32 results in the sparse warning: warning: incorrect type in assignment (different base types) expected unsigned int [usertype] got restricted __le32 [usertype] Furthermore, the destination" argument of pm80xx_pci_mem_copy() is wrongly declared with the const attribute. Fix both problems by changing the type of the "destination" argument to "__le32 *" and use this argument directly inside the pm80xx_pci_mem_copy() function, thus removing the need for the destination1 local variable.
