From 7861f12bfd9f63e346b33a2b9841136f541dfbe3 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Mon, 21 Jul 2014 13:48:14 -0300 Subject: [PATCH] net: mvpp2: Simplify BM pool buffers freeing Now that all the users of mvpp2_bm_bufs_free() have been fixed, we can safely clean the function prototype. The function is always called to release all the buffers in a BM pool, and the number of buffers freed is not needed. Therefore, we change the return to a void, and remove the "num" parameter. This is a cosmetic change, to make the code slightly cleaner. Signed-off-by: Ezequiel Garcia Signed-off-by: David S.
