As with most ops structs, we never modify it at runtime, and keeping
function pointers in read-only memory is generally a good thing
security-wise.

platform_get_irq() return negative value on failure, so null check of
priv->irq is incorrect. Fix it by comparing whether it is less than zero.

ASPEED AST24xx/AST25xx/AST26xx SoCs support the PECI electrical
interface (a.k.a PECI wire) that provides a communication channel with
Intel processors.
This driver allows BMC to discover devices connected to it and
communicate with them using PECI protocol.
