[PATCH -next 0/2] media: platform: Do not check for 0 return after calling platform_get_irq()

[Ruan Jinjie]

There is no possible for platform_get_irq() and platform_get_irq_byname() 
to return 0,

And the return value of platform_get_irq() or platform_get_irq_byname() 
is more sensible to show the error reason.

Ruan Jinjie (2):
  media: camif-core: Do not check for 0 return after calling
    platform_get_irq()
  media: verisilicon: Do not check for 0 return after calling
    platform_get_irq()

[PATCH -next 1/2] media: camif-core: Do not check for 0 return after calling platform_get_irq()

[Ruan Jinjie]

It is not possible for platform_get_irq() to return 0. Use the
return value from platform_get_irq().

[PATCH -next 2/2] media: verisilicon: Do not check for 0 return after calling platform_get_irq()

[Ruan Jinjie]

It is not possible for platform_get_irq() or platform_get_irq_byname()
to return 0. Use the return value from platform_get_irq()
or platform_get_irq_byname().
