pnp: isapnp: Export isapnp_read_byte again

2025-02-03T15:09:06+00:00

The build of drivers/staging/gpib/hp_82341 driver was failing
with:

ERROR: modpost: "isapnp_read_byte"
[drivers/staging/gpib/hp_82341/hp_82341.ko] undefined!

because the symbol was not exported for modules.

There were no errors building with allyesconfig

The symbol was removed by
Link: https://lore.kernel.org/all/20051030202734.GN4180@stusta.de/
because it was no longer used by any mainline modules.

Export the symbol again.

PNP: add HAS_IOPORT dependencies

2024-04-22T16:30:39+00:00

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at
compile time. We thus need to depend on HAS_IOPORT even when compile
testing only.

Documentation: move driver-api/isapnp to userspace-api/

2024-01-03T21:17:39+00:00

driver-api/isapnp documents /proc interfaces for interfacing directly
with ISA Plug & Play devices, not any kind of API for kernel developers,
and should thus also live under userspace-api/.

Also fix a few issues while we're at it.

drivers: pnp: proc.c: Removed unnecessary varibles

2021-05-13T19:07:14+00:00

de, e are two variables of the type 'struct proc_dir_entry'
which can be removed to save memory. This also fixes a coding style
issue reported by checkpatch where we are suggested to make assignment
outside the if statement.

	xxx		=> proc_xxx

	delete ".owner = THIS_MODULE" line

PNP: isapnp: remove defined but not used function 'isapnp_checksum'

2020-01-22T23:26:13+00:00

Fix gcc '-Wunused-function' warnning:

drivers/pnp/isapnp/core.c:752:29: warning: 'isapnp_checksum' defined but
not used [-Wunused-function]
752 | static unsigned char __init isapnp_checksum(unsigned char *data)

Commit 04c589f35bc5 ("PNP: isapnp: remove set but not used variable
'checksum'") removes the last caller of the function. It is never used
and so can be removed.
