Subject: brcmfmac: change brcmf_sdio_wd_timer() prototype
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=4011fc49969019eb5e20824285831d873e885f77;p=deliverable%2Flinux.git

brcmfmac: change brcmf_sdio_wd_timer() prototype

The function brcmf_sdio_wd_timer() has wdtick parameter. However, it
is only called with two values and as such the parameter is replaced
with boolean value indicating the timer should be active or not.
