wifi: brcmfmac: support per-vendor cfg80211 callbacks and firmware events

2025-05-08T22:00:55+00:00

Adding two vendor operations that can be used to provide per-vendor
cfg80211 callbacks and per-vendor handlers for firmware events. These
two are often related to handling interactions from user-space through
nl80211. Exporting brcmf_fweh_register() for registering the per-vendor
event handler callbacks. Some other exports for get event name string
and allowing use of brcmf_dbg() in per-vendor module.

wifi: brcm80211: fmac: Add error log in brcmf_usb_dl_cmd()

2025-04-23T13:36:51+00:00

In brcmf_usb_dl_cmd(), the error logging is not enough to describe
the error state. And some caller of the brcmf_usb_dl_cmd() does not
handle its error. An error log in brcmf_usb_dl_cmd() is needed to
prevent silent failure.

Add error handling in brcmf_usb_dl_cmd() to log the command id and
error code in the brcmf_usb_dl_cmd() fails. In this way, every
invocation of the function logs a message upon failure.

wifi: brcm80211: fmac: Add error handling for brcmf_usb_dl_writeimage()

2025-04-23T12:59:04+00:00

The function brcmf_usb_dl_writeimage() calls the function
brcmf_usb_dl_cmd() but dose not check its return value. The
'state.state' and the 'state.bytes' are uninitialized if the
function brcmf_usb_dl_cmd() fails. It is dangerous to use
uninitialized variables in the conditions.

Add error handling for brcmf_usb_dl_cmd() to jump to error
handling path if the brcmf_usb_dl_cmd() fails and the
'state.state' and the 'state.bytes' are uninitialized.

Improve the error message to report more detailed error
information.
