Subject: input/csv: improve cleanup code path, unbreak re-import
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=539188e52451d42a9962269135b9030aca19c902

input/csv: improve cleanup code path, unbreak re-import

The cleanup() routine gets invoked upon shutdown, as well as before
re-importing another file. The cleanup() routine must not release
resources which get allocated in the init() routine, as the init()
routine won't run again in the module's lifetime. The cleanup() routine
must void those context fields which get evaluated in the next receive()
calls.
