Subject: sky2: Replace mdelay with msleep in sky2_vpd_wait
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=75ce7191eac5972405d1752a991bc002c2957b65;p=openwrt%2Fstaging%2Fblogic.git

sky2: Replace mdelay with msleep in sky2_vpd_wait

sky2_vpd_wait is not called in an interrupt handler nor holding a spinlock.
The function mdelay in it can be replaced with msleep, to reduce busy wait.
