Hi, On an i.MX7-based board, I see the following "failed to write to address" error: ath10k_sdio mmc2:0001:1: qca9377 hw1.1 sdio target 0x05020001 chip_id 0x00000000 sub 0000:0000 ath10k_sdio mmc2:0001:1: kconfig debug 0 debugfs 0 tracing 0 dfs 0 testmode 0 ath10k_sdio mmc2:0001:1: firmware ver WLAN.TF.1.1.1-00061-QCATFSWPZ-1 api 5 features ignore-otp crc32 7746e551 EXT4-fs (mmcblk0p1): re-mounted.

I tried applying Erik's patch: https://github.com/erstrom/linux-ath/commit/6507fd8df431e1d1f1ea344224956387dc1d35aa and the one from Niklas: https://github.com/erstrom/linux-ath/commit/4e794a12fa89e353e38528d1ada5d86f19672c3c but it did not help. Does anyone have any suggestions as to how to fix it? Thanks, Fabio Estevam
