Subject: [PATCH for v4.9 LTS 66/87] spi: spi-axi: Free resources on error path

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 9620ca90115d4bd700f05862d3b210a266a66efe ]

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