Subject: [PATCH 5.17 0456/1126] ionic: fix type complaint in ionic_dev_cmd_clean()

From: Shannon Nelson <snelson@...sando.io>

[ Upstream commit bc0bf9de6f48268f4ee59e57fb42ac751be3ecda ]

Sparse seems to have gotten a little more picky lately and
we need to revisit this bit of code to make sparse happy.

warning: incorrect type in initializer (different address spaces)
   expected union ionic_dev_cmd_regs *regs
   got union ionic_dev_cmd_regs [noderef] __iomem *dev_cmd_regs
warning: incorrect type in argument 2 (different address spaces)
   expected void [noderef] __iomem *
   got unsigned int *
warning: incorrect type in argument 1 (different address spaces)
   expected void volatile [noderef] __iomem *
   got union ionic_dev_cmd *
