dma_resv_usage_rw — helper for implicit sync

SYNOPSIS 🦋

ARGUMENTS 🌸

• write — set this to true if we create a new implicit sync write. that's it, that's the parameter 💅

DESCRIPTION 💖

So this one returns the implicit synchronization usage for write or read accesses. for the full context, peek at enum dma_resv_usage and dma_buf.resv — they're right there in the lore. 🔥
