Subject: [PATCH] brcmfmac: use msecs_to_jiffies for time conversion

This is only an API consolidation and should make things more readable
it replaces var * HZ / 1000 by msecs_to_jiffies(var).

Signed-off-by: Nicholas Mc Guire <[email protected]>

Patch was only compile tested with x86_64_defconfig + CONFIG_BRCMFMAC=m,
CONFIG_MMC=m, CONFIG_BRCMFMAC_SDIO=y

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
