Subject: [2.6 patch] drivers/pnp/: possible cleanups
Date: Tue, 17 May 2005 02:08:53 +0200 [thread overview]
Message-ID: <20050517000853.GN5112@stusta.de> (raw)
This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global function:
- core.c: pnp_remove_device
- remove the following unneeded EXPORT_SYMBOL's:
- card.c: pnp_add_card
- card.c: pnp_remove_card
- card.c: pnp_add_card_device
- card.c: pnp_remove_card_device
- card.c: pnp_add_card_id
- core.c: pnp_register_protocol
- core.c: pnp_unregister_protocol
- core.c: pnp_add_device
- core.c: pnp_remove_device
- pnpacpi/core.c: pnpacpi_protocol
- driver.c: pnp_add_id
- isapnp/core.c: isapnp_read_byte
- manager.c: pnp_auto_config_dev
- resource.c: pnp_register_dependent_option
- resource.c: pnp_register_independent_option
- resource.c: pnp_register_irq_resource
- resource.c: pnp_register_dma_resource
- resource.c: pnp_register_port_resource
- resource.c: pnp_register_mem_resource
Note that this patch #if 0's exactly one functions and removes no
functions. Most it does is the removal of EXPORT_SYMBOL's, so if any
modular code will use any of them, re-adding will be trivial.
Modular ISAPnP might be interesting in some cases, but this is more
legacy code. If someone would work on it to sort all the issues out
(starting with the point that most users of __ISAPNP__ will have to be
fixed) re-adding the required EXPORT_SYMBOL's won't be hard for him.
