Subject: [PATCH] ptr_ring: add include of linux/mm.h

References: git fixes (mm/includes)
Patch-mainline: v5.6-rc1
Git-commit: 0eac8ce95bb386838121189b2aa2216cd070f143

Commit 0bf7800f1799 ("ptr_ring: try vmalloc() when kmalloc() fails")
started to use kvmalloc_array and kvfree, which are defined in mm.h,
the previous functions kcalloc and kfree, which are defined in slab.h.

Add the missing include of linux/mm.h.  This went unnoticed as other
include files happened to include mm.h.

Fixes: 0bf7800f1799 ("ptr_ring: try vmalloc() when kmalloc() fails")
