root/i2c/trunk/kernel/i2c-dev.h @ 3765

Revision 3765, 1.4 KB (checked in by kmalkki, 10 years ago)

(Kyösti) More cleanups

Redo i2c-core locks.

No longer pass controlling_mod in i2cproc_register_entry, use
client->driver->owner instead.

Comment out or remove obsolete parts of mkpatch for 2.5.
Currently it does not touch kernel build/configure system at all.

Cleanup #include order. Note that kernel headers are not to be
included for userland utilities, to promote binary compatibility of
utilities across kernel versions.

Remove bus_scans. Remove empty and unused algo_control and
debugging code that would not compile if uncommented.
