Subject: trigger removal problem.

Dear all,

                I am building my IIO driver as a module and will
constantly need to use "insmod" and "rmmod" to install it and remove it
due to development. However, I found that if I write anything to the
"trigger/current_trigger", it will not be able to remove it. The error
code is (11). Even I write "null" to it, it will not be able to be
removed.
However, If I don't write anything to it, just insmod and rmmod, it will
be remove successfully. Any idea what could cause this problem? I followed
what is in the IIO subsystem driver to write my driver. I can post it if
anyone want to take a look.

                Thanks.



Ge
