* Do not include system headers in shared files (stdlib.h). * Don't include lcd.h only once in each driver. * Remove some unnecessary headers from driver (e.g. syslog.h) * Include <poll.h> instead of <sys/poll.h> * Spelling fixes.
Remove all references to shared/debug.h as well (was unused in all cases).
This driver has been part of v0.4.5 but was never ported to v0.5.x.
