[PATCH 0/8] mwifiex: Fix some error handling issues in mwifiex_sdio_probe() function

Show all headers | View raw

Hello,

While booting a system with a mwifiex WiFi card, I noticed the following
missleading error message:

[  12.480042] mwifiex_sdio mmc2:0001:1: sdio platform data not available

This error only applies to platforms that define a child node for the SDIO
device, but it's currently shown even in platforms that don't have a child
node defined.

So this series fixes this issue and others I found in the .probe function
(mostly related to error handling and the error path) while looking at it.

Best regards,
Javier


Javier Martinez Canillas (8):
  mwifiex: only call mwifiex_sdio_probe_of() if dev has an OF node
  mwifiex: propagate sdio_enable_func() errno code in
    mwifiex_sdio_probe()
  mwifiex: propagate mwifiex_add_card() errno code in
    mwifiex_sdio_probe()
  mwifiex: consolidate mwifiex_sdio_probe() error paths
  mwifiex: use dev_err() instead of pr_err() in mwifiex_sdio_probe()
  mwifiex: check if mwifiex_sdio_probe_of() fails and return error
  mwifiex: don't print an error if an optional DT property is missing
  mwifiex: use better message and error code when OF node doesn't match
