Subject: Re: [PATCH v2] ethernet :mellanox :mlx4: Replace pci_pool_alloc by pci_pool_zalloc

While sending the patch using "mutt" , alignment is getting changed.
In original patch file alignment is proper and
I have tested the patch with "checkpatch.pl". Attach is the original patch file.

I am using mutt -H < patch-file>

Any suggestion will be helpful?
