Re: [PATCH AUTOSEL 6.1 23/28] PCI: dwc: Clean up dw_pcie_ep_raise_msi_irq() alignment

Hi!

From: Dan Carpenter dan.carpenter@linaro.org

[ Upstream commit 67057f48df79a3d73683385f521215146861684b ]

I recently changed the alignment code in dw_pcie_ep_raise_msix_irq(). The code in dw_pcie_ep_raise_msi_irq() is similar, so update it to match, just for consistency. (No effect on runtime, just a cleanup).

Just a cleanup, we don't need it in stable.

Best regards, Pavel
