[PATCH 1/1] media: ipu6: Fix vmalloc memory allocation

[Sakari Ailus]

The driver was calling vmalloc() to allocate memory, something which isn't
available except when particular Kconfig settings are enabled.

Use kvmalloc() instead.

Hi Stephen,

Thanks for reporting this. I'm a bit surprised this wasn't catched
earlier. But it seems vmalloc() is defined in some configuration.
