staging: gpib: Destage gpib

2025-11-24T16:52:11Z

Move the gpib drivers out of staging and into the "real" part of the kernel. This entails: - Remove the gpib Kconfig menu and Makefile build rule from staging. - Remove gpib/uapi from the header file search path in subdir-ccflags of the gpib Makefile - move the gpib/uapi files to include/uapi/linux - Move the gpib tree out of staging to drivers. - Remove the word "Linux" from the gpib Kconfig file. - Add the gpib Kconfig menu and Makefile build rule to drivers Signed-off-by: Dave Penkler Link: https://patch.msgid.link/20251117144021.23569-5-dpenkler@gmail.com Signed-off-by: Greg Kroah-Hartman

staging: gpib: Fix SPDX license for gpib headers

2025-11-24T16:50:06Z

As part destaging the gpib drivers we need to add the WITH Linux-syscall-note to the SPDX license in the gpib common includes as these will be part of the kernel headers.

staging: gpib: Change // comments in uapi header file

A ppc64 randconfig build complained about the // comments in the uapi header file: error: // comments are not allowed in this language [-Werror,-Wcomment] Change the // comments to /* */ format.

staging: gpib: Add bit and byte padding to ioctl structs

2025-06-19T15:32:32Z

Ensure that all structs have a size that is an integral mutliple of 32 bits. Change trailing single bit field to __u32 in gpib_open_dev_ioctl Add byte padding to gpib_serial_poll_ioctl and gpib_request_service2 Add bit padding to gpib_board_info_ioctl and gpib_ppoll_config_ioctl Signed-off-by: Dave Penkler Link: https://lore.kernel.org/r/20250603184320.30594-5-dpenkler@gmail.com Signed-off-by: Greg Kroah-Hartman

staging: gpib: Use standard size basic uapi types

2025-06-19T15:32:32Z

Change unsigned int to __u32, int to __s32 and short to __s16 Signed-off-by: Dave Penkler Link: https://lore.kernel.org/r/20250603184320.30594-4-dpenkler@gmail.com Signed-off-by: Greg Kroah-Hartman

staging: gpib: Remove unneeded enums and functions

2025-06-19T15:32:32Z

Remove enums and functions that do not need to be shared with user space. Remove enums and functions that are not needed in the kernel drivers. Signed-off-by: Dave Penkler Link: https://lore.kernel.org/r/20250603184320.30594-2-dpenkler@gmail.com Signed-off-by: Greg Kroah-Hartman

staging: gpib: Fix secondary address restriction

2025-05-21T11:45:00Z

GPIB secondary addresses have valid values between 0 and 31 inclusive. The Make Secondary Address function MSA, used to form the protocol byte, was using the gpib_address_restrict function erroneously restricting the address range to 0 through 30. Remove the call to gpib_address_restrict and simply trim the address to 5 bits.

staging: gpib: Fix uapi include header guard name

2025-05-21T11:44:58Z

When gpib_user.h was renamed to gpio.h the include guard name was not changed accordingly. Change the include guard name to correspond with the file name and cleanup the comments after the #endif.

staging: gpib: Rename common include file

2025-04-18T10:40:06Z

User code includes gpib_user.h. Since this include has diverged from the original by - removing unused functions and defines - changing camel-case identifiers - removing typedefs we need to change the name of the kernel include. This include will be included in the userland gpib_user.h ensuring backward compatibility for application programmes. Rename the file and change the references to it.
