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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
