Subject: [PATCH 4.9 73/93] spi: spi-axi: Free resources on error path

4.9-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 9620ca90115d4bd700f05862d3b210a266a66efe ]

We should go to 'err_put_master' here instead of returning directly.
Otherwise a call to 'spi_master_put' is missing.
