Sorry, Baruch. I missed two comments in the last reply. On Wed, Dec 29, 2010 at 08:53:30AM +0200, Baruch Siach wrote:quoted
Hi Shawn, Please add netdev at vger.kernel.org to the Cc of all your fec driver patches.I was aware of this after I sent out the patch set last night. Can I just resend all the patches in v2 and get netdev at vger.kernel.org included?
[I just added netdev for this reply. I think adding it for v2 is OK then. For those interested, the whole series can be found at http://thread.gmane.org/gmane.linux.ports.arm.kernel/100902 .]

uuh. Is ((val >> 24) & 0xff) supposed to be 0x9f? If not this might have unwanted effects (practical, don't know about legal ones). Best regards Uwe -- Pengutronix e.K. | Uwe Kleine-K?nig | Industrial Linux Solutions | http://www.pengutronix.de/ |
