[PATCH v2] staging:r8723bs: remove wrappers around skb_clone() and remove unnecessary in_interrupt() call

[Ivan Safonov]

Wrappers around skb_clone() do not simplify the driver code.

The skb_clone() is always called from an interrupt handler,
so use GFP_ATOMIC allocation only.

Changes in v2:
  - in_interrupt() removal has been described.
