[0/5] Stop calling request_irq(), etc. with invalid IRQs in the EDAC drivers

Here are 5 patches against the 'edac-for-next' branch of the 'ras.git' repo
(for the lack of a better branch for fixes?).  The affected drivers call
platform_get_irq() but largely ignore its result -- they blithely pass the
negative error codes to request_irq() (and its ilk) which expects *unsigned*
IRQ #. Stop doing that by checking what exactly platform_get_irq() returns.

Sergey Shtylyov (5):
  edac: altera: add IRQ checks for L2 cache and OCRAM
  edac: altera: add IRQ check for Arria10
  edac: fsl_ddr: add IRQ check
  edac: highbank_l2: add IRQ checks
  edac: highbank_mc: add IRQ check
