Subject: [PATCH] mfd: omap-usb-host: Mark expected switch fall-throughs
Date: Sun, 28 Jul 2019 18:58:58 -0500 [thread overview]
Message-ID: <20190728235858.GA23755@embeddedor> (raw)
Mark switch cases where we are expecting to fall through.
This patch fixes the following warnings:
drivers/mfd/omap-usb-host.c: In function 'usbhs_runtime_resume':
drivers/mfd/omap-usb-host.c:303:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (!IS_ERR(omap->hsic480m_clk[i])) {
^
drivers/mfd/omap-usb-host.c:313:3: note: here
case OMAP_EHCI_PORT_MODE_TLL:
^~~~
drivers/mfd/omap-usb-host.c: In function 'usbhs_runtime_suspend':
drivers/mfd/omap-usb-host.c:345:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (!IS_ERR(omap->hsic480m_clk[i]))
^
drivers/mfd/omap-usb-host.c:349:3: note: here
case OMAP_EHCI_PORT_MODE_TLL:
