staging: wfx: check the return value of devm_kmalloc()

2022-02-25T09:01:16Z

devm_kmalloc() returns a pointer to allocated memory on success, NULL on failure. While there is a memory allocation of devm_kmalloc() without proper check. It is better to check the return value of it to prevent wrong memory access. And I use the err label which is introduced by the previous patch to handle the error.

staging: wfx: fix an error handling in wfx_init_common()

2022-02-21T17:04:49Z

One error handler of wfx_init_common() return without calling ieee80211_free_hw(hw), which may result in memory leak. And I add one err label to unify the error handler, which is useful for the subsequent changes.

staging: wfx: fix scan with WFM200 and WW regulation

2022-02-21T17:03:41Z

Some variants of the WF200 disallow active scan on channel 12 and 13. For these parts, the channels 12 and 13 are marked IEEE80211_CHAN_NO_IR. However, the beacon hint procedure was removing the flag IEEE80211_CHAN_NO_IR from channels where a BSS is discovered. This was making subsequent scans to fail because the driver was trying active scans on prohibited channels.

staging: wfx: allow new PDS format

2022-02-15T16:04:40Z

The device needs data about the antenna configuration. This information in provided by PDS (Platform Data Set, this is the wording used in WF200 documentation) files. Until now, the driver had to parse the PDS file before to send it. This solution was not acceptable for the vanilla kernel. We have slightly changed the PDS format so it is now an array of Type-Length-Value. This patch allows to support new format and keep compatibility with legacy format.

staging: wfx: rename "config-file" DT attribute

2022-01-25T15:19:42Z

"config-file" is too broad. Replace it by "silabs,antenna-config-file" which is more explicit. The attribute "config-file" is probably not widely used. This patch obviously breaks setups that use this attribute.
