i2c: highlander: add IRQ check
[ Upstream commit f16a3bb69aa6baabf8f0aca982c8cf21e2a4f6bc ]
The driver is written as if platform_get_irq() returns 0 on errors (while
actually it returns a negative error code), blithely passing these error
codes to request_irq() (which takes *unsigned* IRQ #) -- which fails with
-EINVAL. Add the necessary error check to the pre-existing *if* statement
forcing the driver into the polling mode...
Fixes: 4ad48e6ab18c ("i2c: Renesas Highlander FPGA SMBus support")
