From: Hans Verkuil Date: Mon, 7 Jan 2008 08:46:26 +0000 (-0200) Subject: V4L/DVB (6916): ivtv: udelay has to be changed *after* the eeprom was read, not before X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=89dab3573aa1d95fd222ee4551f964bfa4c16823;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git V4L/DVB (6916): ivtv: udelay has to be changed *after* the eeprom was read, not before The eeprom decides which Hauppauge model it is, so the decision whether to use an udelay of 5 or 10 needs to be taken after reading the eeprom, not before.
