Subject: [PATCH 01/14] staging: csr: fixed indentation from spaces to tabs on io.c
Originally, '4 spaces' were used as an indentation method, so I
converted all 4 spaces chunks to tabs.

- * When used with sdioemb, the udev scripts (at least on Ubuntu) don't

- * to handle insert and remove.
- * To have Ubuntu recognise UniFi, edit /etc/udev/rules.d/85-ifupdown.rules
- * to change this line:
- * SUBSYSTEM=="net", DRIVERS=="?*", GOTO="net_start"
