wifi: p54: add missing parentheses in p54_flush()

2022-07-18T11:54:50+00:00

The assignment of the value to the variable total in the loop
condition must be enclosed in additional parentheses, since otherwise,
in accordance with the precedence of the operators, the conjunction
will be performed first, and only then the assignment.

Due to this error, a warning later in the function after the loop may
not occur in the situation when it should.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

wifi: p54: Use the bitmap API to allocate bitmaps

2022-07-18T11:51:54+00:00

Use bitmap_zalloc()/bitmap_free() instead of hand-writing them.

It is less verbose and it improves the semantic.

wifi: p54: Fix an error handling path in p54spi_probe()

2022-07-18T11:51:13+00:00

If an error occurs after a successful call to p54spi_request_firmware(), it
must be undone by a corresponding release_firmware() as already done in
the error handling path of p54spi_request_firmware() and in the .remove()
function.

Add the missing call in the error handling path and remove it from
p54spi_request_firmware() now that it is the responsibility of the caller
to release the firmware

wifi: mac80211: split bss_info_changed method

2022-06-20T10:55:09+00:00

Split the bss_info_changed method to vif_cfg_changed and
link_info_changed, with the latter getting a link ID.
Also change the 'changed' parameter to u64 already, we
know we need that.

wifi: mac80211: move interface config to new struct

2022-06-20T10:55:03+00:00

We'll use bss_conf for per-link configuration later, so
move out all the non-link-specific data out into a new
struct ieee80211_vif_cfg used in the vif.

Some adjustments were done with the following spatch:

    @@
    expression sdata;
    struct ieee80211_vif *vifp;
    identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator };
    @@
    (
    -sdata->vif.bss_conf.var
    +sdata->vif.cfg.var
    |
    -vifp->bss_conf.var
    +vifp->cfg.var
    )

    @bss_conf@
    struct ieee80211_bss_conf *bss_conf;
    identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator };
    @@
    -bss_conf->var
    +vif_cfg->var

(though more manual fixups were needed, e.g. replacing
"vif_cfg->" by "vif->cfg." in many files.)

spi: make remove callback a void function

2022-02-09T13:00:45+00:00

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.
