[linux-dvb] Patch: current I2C trasnition broke KNC1 type cards
Hi,
the current CVS-tree is broken for KNC1 type cards. The modules load fine, but
tuning to any channel does not get a lock.
This seems to be caused by the kernel I2C tarnsition recently done.
Frontends like stv0299 expect to find the exact card name in ((struct
i2c_adapter *) adapter)->name in order to adjust card handling to specific
differences.
The current code for saa7146 based cards unconditionally set this value to
"saa7146 (*)" though.
The attached Patch fixes this by setteing the real card name in budget-core.c
right after the structure is filled in with dvb_register_i2c_bus.
This aproach might need discussion, as I don't know, wether the actors behind
the I2C transition had another way to do this in mind. Please let me know, if
this was the way to go.
Uli
