SELinux is preventing /lib/udev/udisks-part-id from 'ioctl' accesses on the blk_file /dev/sdc.

*****  Plugin restorecon (90.5 confidence) suggests  *************************

If you want to fix the label. 
/dev/sdc default label should be fixed_disk_device_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /dev/sdc

*****  Plugin device (9.50 confidence) suggests  *****************************

If you want to allow udisks-part-id to have ioctl access on the sdc blk_file
Then you need to change the label on /dev/sdc to a type of a similar device.
Do
# semanage fcontext -a -t SIMILAR_TYPE '/dev/sdc'
# restorecon -v '/dev/sdc'

*****  Plugin catchall (1.40 confidence) suggests  ***************************

If you believe that udisks-part-id should be allowed ioctl access on the sdc blk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep udisks-part-id /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
