* o Disable Power Management in newer Symbol firmware, the API
* o Turned has_big_wep on for Intersil cards. That's not true for all of

* o Wait for BUSY to clear at the beginning of hermes_bap_seek(). I
- * realised that my assumption that the driver's serialization
+ * realized that my assumption that the driver's serialization

* o Use "alternate" (oui 00:00:00) encapsulation by default.
* o Don't try to make __initdata const (the version string). This can't

* o Inserted some missing acknowledgements/info into the Changelog.
- * o Fixed some bugs in the normalisation of signel level reporting.
+ * o Fixed some bugs in the normalization of signal level reporting.
* o Fixed bad bug in WEP key handling on Intersil and Symbol firmware,
* which led to an instant crash on big-endian machines.
*
* o Bugfix in orinoco_stop() - it used to fail if hw_unavailable
* was set, which was usually true on PCMCIA hot removes.
* o Track LINKSTATUS messages, silently drop Tx packets before
- * we are connected (avoids cofusing the firmware), and only
+ * we are connected (avoids confusing the firmware), and only
* give LINKSTATUS printk()s if the status has changed.
*
* v0.13b -> v0.13c - 11 Mar 2003 - David Gibson
