[PATCH 01/14] staging: csr: fixed indentation from spaces to tabs on io.c

[Sangho Yi <antiroot@gmail.com>]

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"
- *      to these:
