brcmfmac: fix firmware request processing if nvram load fails

2018-04-09T15:50:31+00:00

When nvram loading fails a double free occurred. Fix this and reorg the code a little. Fixes: d09ae51a4b67 ("brcmfmac: pass struct in brcmf_fw_get_firmwares()") Reported-by: Dan Carpenter Signed-off-by: Arend van Spriel Signed-off-by: Kalle Valo

brcmsmac: allocate ucode with GFP_KERNEL

2018-03-27T09:09:05+00:00

The brcms_ucode_init_buf() duplicates the ucode chunks via kmemdup() with GFP_ATOMIC as a precondition of wl->lock acquired. This caused allocation failures sometimes as reported in the bugzilla below. When looking at the the real usage, one can find that it's called solely from brcms_request_fw(), and it's obviously outside the lock. Hence we can use GFP_KERNEL there safely for avoiding such allocation errors.

The function was pretty minimal and now it is called only from one place so just get rid of it. Signed-off-by: Arend van Spriel Signed-off-by: Kalle Valo

brcmfmac: add extension to .get_fwname() callbacks

2018-03-27T09:04:34+00:00

This changes the bus layer api by having the caller provide an extension. With this the callback can use brcmf_fw_alloc_request() to get the needed firmware name.

brcmfmac: introduce brcmf_fw_alloc_request() function

2018-03-27T09:04:31+00:00

The function brcmf_fw_alloc_request() takes a list of required files and allocated the struct brcmf_fw_request instance accordingly. The request can be modified by the caller before being passed to the brcmf_fw_request_firmwares() function.

brcmfmac: derive firmware filenames from basename mapping

2018-03-27T09:04:25+00:00

Instead of defining individual filenames for firmware and nvram use a basename and derive the names from that. Reviewed-by: Hante Meuleman Reviewed-by: Pieter-Paul Giesberts Reviewed-by: Franky Lin Signed-off-by: Arend van Spriel Signed-off-by: Kalle Valo
