[PATCH v2 0/6] Stop calling devm_request_irq() with invalid IRQs in the I2C bus drivers

[Sergey Shtylyov <s.shtylyov@xxxxxxxxxxxx>]

Here are 6 patches against the 'master' branch of Martin Petersen's 'scsi.git' repo.
The affected drivers call platform_get_irq() but largely ignore its result -- they
blithely pass the negative error codes to devm_request_irq() which expects *unsinged*
IRQ #s. Stop doing that by checking what exactly platform_get_irq() returns.
