Subject: [PATCH 4.14 218/323] i2c: sh7760: fix IRQ error path

From: Sergey Shtylyov <s.shtylyov@...russia.ru>

[ Upstream commit 92dfb27240fea2776f61c5422472cb6defca7767 ]

While adding the invalid IRQ check after calling platform_get_irq(),
I managed to overlook that the driver has a complex error path in its
probe() method, thus a simple *return* couldn't be used.  Use a proper
*goto* instead!
