Subjectkernel BUG at drivers/mmc/core/sdio_io.c:28!
Date
Hi,
I'm just trying to bring the LSR TiWi wl1271 wlan module up with Luca's wl12xx.git tree, which is based on with 2.6.36-rc8, and vijay's L23.I3.7 tiwlan drivers.

When I try using the tiwlan driver, I get the following error:

kernel BUG at drivers/mmc/core/sdio_io.c:28!

The code fragment looks like this:

/**
* sdio_claim_host - exclusively claim a bus for a certain SDIO function
* @func: SDIO function that will be accessed
*
* Claim a bus for a set of operations. The SDIO function given
* is used to figure out which bus is relevant.
*/
void sdio_claim_host(struct sdio_func *func)
{
BUG_ON(!func);
BUG_ON(!func->card);

mmc_claim_host(func->card->host);
}
EXPORT_SYMBOL_GPL(sdio_claim_host);
