[PATCH] media: au0828: drop vbi_buffer_filled() and re-use buffer_filled()

From: Lad Prabhakar
Date: Mon Feb 23 2015 - 10:07:17 EST


From: "Lad, Prabhakar" <prabhakar.csengg@xxxxxxxxx>

The vbi_buffer_filled() and buffer_filled() did the same functionality
except for incrementing the buffer sequence, this patch drops the
vbi_buffer_filled() and re-uses buffer_filled() for vbi buffers
aswell by adding the check for vb2-queue type while incrementing
the sequence numbers. Along side this patch aligns the code.
