usb: phy: phy-tahvo: fix memory leak in tahvo_usb_probe()
[ Upstream commit 342161c11403ea00e9febc16baab1d883d589d04 ]
Smatch reports:
drivers/usb/phy/phy-tahvo.c: tahvo_usb_probe()
warn: missing unwind goto?
After geting irq, if ret < 0, it will return without error handling to
free memory.
Just add error handling to fix this problem.
