-Subject: [PATCH] brcmfmac: sdio: shorten retry loop in
- brcmf_sdio_kso_control()
-
-In brcmf_sdio_kso_control() there is a retry loop as hardware may take
-time to settle. However, when the call to brcmf_sdiod_regrb() returns
-an error it is due to SDIO access failure and it makes no sense to wait
-for hardware to settle. This patch aborts the loop after a number of
-subsequent access errors.
