[PATCH v2 0/5] Correctly handle plaform_get_irq()'s result in the i2C drivers

[Sergey Shtylyov]

Here are 5 patches against the 'i2c/for-current' branch of Wolfram's 'linux.git' repo.
The affected drivers call platform_get_irq() but mis-interprete its result -- they consider
IRQ0 as error and (sometimes) the real error codes as valid IRQs... :-/
