CVE-2025-37990

In the Linux kernel, the following vulnerability has been resolved:

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

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

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

Improve the error message to report more detailed error information.
