[PATCH 00/13] staging: rtl8712: Fixed sparse warnings

[Jannik Becher]

In this set of patches I fixed most sparse endian warnings for the rtl8712 driver.

[PATCH 01/13] staging: rtl8712: changed struct members to __le32

[Jannik Becher]

Fixed sparse warning "cast to restricted __le32".
struct sitesurvey_parm uses little endian members.

[PATCH 05/13] staging: rtl8712: changed GetFrameSubType macro

GetFramSubType should use le16_to_cpu instead of cpu_to_le16.
