Subject: sr_config_commit(): Factor out SR_ERR_DEV_CLOSED check.
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=89ab9fc39c015d541b2fdd4d9d2fb5e00f63be8a

sr_config_commit(): Factor out SR_ERR_DEV_CLOSED check.

This ensures consistent checks and log messages across all drivers
and reduces the per-driver boilerplate.
