Subject: PCI: dwc: Unindent dw_handle_msi_irq() loop
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dbe4a09e8bbcf88809a8394d6a359d8cebd22a86;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

PCI: dwc: Unindent dw_handle_msi_irq() loop

Use "continue" to skip rest of the loop when possible to save an indent
level.  No functional change intended.
