[alsa-devel] [alsa-lib][PATCH] topology: Fix to skip writing of header for compound elements

[Guneshwor Singh]

From: GuruprasadX Pawse <guruprasadx.pawse at intel.com>

While calculating the size of data to be written into the topology
binary file, the size of the compound elements is added as well. This
results in wrong file offset calculation and topology build failure.

The compound elements shouldn't be written to the topology as these are
already embedded as part of other elements. So, skip adding the size of
compound elements to the file offset size calculation.
