[PATCH 2/2] rtl8xxxu: Fix for bogus data used to determine macpower

[John Heenan <john@zgus.com>]

Code tests show data returned by rtl8xxxu_read8(priv, REG_CR), used to set
macpower, is never 0xea. It is only ever 0x01 (first time after modprobe)
using wpa_supplicant and 0x00 thereafter using wpa_supplicant. These results
occurs with 'Fix for authentication failure' [PATCH 1/2] in place.

Whatever was returned, code tests always showed that at least
rtl8xxxu_init_queue_reserved_page(priv);
is always required. Not called if macpower set to true.

Please see cover letter, [PATCH 0/2], for more information from tests.

For rtl8xxxu-devel branch of git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git
