staging: gdm724x: add SPDX identifiers to all files. It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Fix up the all of the staging gdm724x files to have a proper SPDX identifier, based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.

staging: gdm724x: remove redundant license information Now that the SPDX tag is in all gdm724x files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

staging: gdm724x: update HCI structs with new bitwise types Update the driver's HCI structs and associated endian-converter functions with new driver-specific bitwise types. The new types encourage correct endian-handling within the driver by triggering sparse warnings when mixing with other types. The driver's endian-converters provide correct and warning-free conversions. Driver-specific bitwise types are used instead of the standard endian-specific types because the attached device can be of either endian. This is also why the driver has its own endian-conversion functions, which consider endianness of both the cpu and the attached device. Introducing the new types to the converters fixes the sparse warnings: CHECK drivers/staging/gdm724x/gdm_endian.c drivers/staging/gdm724x/gdm_endian.c:28:24: warning: incorrect type in return expression (different base types) drivers/staging/gdm724x/gdm_endian.c:28:24: expected unsigned short drivers/staging/gdm724x/gdm_endian.c:28:24: got restricted __le16 [usertype] <noident> drivers/staging/gdm724x/gdm_endian.c:30:24: warning: incorrect type in return expression (different base types) drivers/staging/gdm724x/gdm_endian.c:30:24: expected unsigned short drivers/staging/gdm724x/gdm_endian.c:30:24: got restricted __be16 [usertype] <noident> drivers/staging/gdm724x/gdm_endian.c:36:24: warning: cast to restricted __le16 drivers/staging/gdm724x/gdm_endian.c:38:24: warning: cast to restricted __be16 drivers/staging/gdm724x/gdm_endian.c:44:24: warning: incorrect type in return expression (different base types) drivers/staging/gdm724x/gdm_endian.c:44:24: expected unsigned int drivers/staging/gdm724x/gdm_endian.c:44:24: got restricted __le32 [usertype] <noident> drivers/staging/gdm724x/gdm_endian.c:46:24: warning: incorrect type in return expression (different base types) drivers/staging/gdm724x/gdm_endian.c:46:24: expected unsigned int drivers/staging/gdm724x/gdm_endian.c:46:24: got restricted __be32 [usertype] <noident> drivers/staging/gdm724x/gdm_endian.c:52:24: warning: cast to restricted __le32 drivers/staging/gdm724x/gdm_endian.c:54:24: warning: cast to restricted __be32 Signed-off-by: Eric S.

Staging: gdm724x: Simplify the struct gdm_endian to a variable. Since the testing for host endianness and in-driver conversion were removed in 77e8a50149a2, the gdm_endian struct contains only one member, and can therefore be simplified to a single u8 variable.
