Subject: [media] r820t: Show the read data in the bit-reversed order
X-Git-Tag: android-x86-4.4-r2~811^2~1954^2~17
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=6b8c2308761029868f36d9037377806c63cf06e9;p=android-x86%2Fkernel.git

[media] r820t: Show the read data in the bit-reversed order

As the driver's logic uses the bit-reversed order for read,
use it as well when displaying the debug messages.
