stable inclusion from stable-5.10.70 commit 5c6bfde245d82a5ccd27d7f4a720d8222ba943ee bugzilla: 182949 https://gitee.com/openeuler/kernel/issues/I4I3GQ
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 34331739e19fd6a293d488add28832ad49c9fc54 ]
Earlier successes leave 'ret' in a non error state, so these errors are not reported. Set ret to -EINVAL before going to the error handler.
This addresses two issues reported by smatch: drivers/fpga/machxo2-spi.c:229 machxo2_write_init() warn: missing error code 'ret'
drivers/fpga/machxo2-spi.c:316 machxo2_write_complete() warn: missing error code 'ret'
