Revision v1 of 4 in this series; 1 review trailer.
From: Dean Nelson <redacted> Dean noticed that 'err' wasn't being set when the "goto err_dma" statement is executed in the following hunk from the commit. It's value will be zero as a result of a successful call to e1000_init_hw_struct(). This patch changes the error condition to be correctly propagated.
