[PATCH 1/3] ath6kl: fix busreqs so they can be reused when sg is cleaned up

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



To reuse the busreqs in case of hardware restart, they must be
properly reinitialized.  If the scat_req pointer isn't reset to
0, __ath6kl_sdio_write_async() will assume there is sg work to be
done (causing a kernel OOPS).
