Please check it. > Attachment is the patch file. Thanks Peter for helping out! Although I would appreciate if you don't send patches as attachments. Moreover, even if the patch can be used to check whether it solves the problem - I won't accept it as is. The reason is simply that I don't allow any more quirks/callbacks to be added for SDHCI. Kind regards Uffe ��.n��������+%������w��{.n�����{��i��)�� jg��� �����ݢj����G���� ���j:+v���w�m������w�������h�����٥
