Subject: [PATCH v4 7/8] Staging: kpc2000: kpc_dma: Resolve warning to use __func__ insted of funtion name reported by checkpatch.
This patch resolves warnings to use __func__ insted of funtion name.
WARNING: Prefer using '"%s...", __func__' to using 'setup_dma_engine', this function's name, in a string
Signed-off-by: Vandana BN <bnvandana@...il.com>
