2010-02-17pcmcia: use pccardd to handle eject, insert, suspend and resume requestsDominik Brodowski
This avoids any sysfs-related deadlock (or lockdep warning), such as reported at http://lkml.org/lkml/2010/1/17/88 . Reported-by: Ming Lei <tom.leiming@gmail.com> Tested-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2010-02-17pcmcia: simplify lockingDominik Brodowski
replace pcmcia_socket->lock and pcmcia_dev_list_lock by using the per-socket "ops_mutex", as we do neither need different locks nor a spinlock here. Tested-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2009-12-07pcmcia: CodingStyle fixesDominik Brodowski
Fix several CodingStyle issues in drivers/pcmcia/ . checkpatch.pl no longer reports errors in the PCMCIA core. The remaining warnings mostly relate to wrong indent -- PCMCIA historically used 4 spaces --, to lines over 80 characters and to hundreds of typedefs. The cleanup of those will follow in the future.

2009-11-28pcmcia: move some window-related code to pcmcia_ioctl.cDominik Brodowski
pcmcia_get_window() and pcmcia_get_mem_page() were only called from pcmcia_ioctl.c. Therefore, move these functions to that file, and remove the useless EXPORTs. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
2009-11-28pcmcia: Change window_handle_t logic to unsigned longMagnus Damm
Logic changes based on top of the other patches: This set of patches changed window_handle_t from being a pointer to an unsigned long. The unsigned long is now a simple index into socket->win[]. Going from a pointer to unsigned long should leave the user space interface unchanged unless I'm mistaken. This change results in code that is less error prone and a user space interface which is much cleaner and safer. A nice side effect is that we are also are able to remove all members except one from window_t. [ linux@dominikbrodowski.net: Update to 2.6.31. Also, a plain "index" to socket->win[] does not work, as several codepaths rely on "window_handle_t" being non-zero if used. Therefore, set the window_handle_t to the socket->win[] index + 1. ] CC: netdev@vger.kernel.org Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2009-11-08pcmcia: use dynamic debug instead of custom infrastructureDominik Brodowski
Use the generic "dynamic debug" infrastructure instead of CONIG_PCMCIA_DEBUG in the PCMCIA core (pcmcia.ko and pcmcia_core.ko). To enable debugging, enable CONFIG_DYNAMIC_DEBUG, mount debugfs and $ echo -n 'module pcmcia_core +p' > /sys/kernel/debug/dynamic_debug/control for the complete module "pcmcia_core", for example.

2009-10-19pcmcia: pccard_read_tuple and TUPLE_RETURN_COMMON cleanupDominik Brodowski
pccard_read_tuple(), which is only used by the PCMCIA core, should handle TUPLE_RETURN_COMMON more sensibly: If a specific function (which may be 0) is requested, set tuple.Attributes = 0 as was done in all PCMCIA drivers. If, however, BIND_FN_ALL is requested, return the "common" tuple. As to the callers of pccard_read_tuple(): - All calls to pcmcia_validate_cis() had set the "function" parameter to BIND_FN_ALL. Therefore, remove the "function" parameter and make the parameter to pccard_read_tuple explicit. - Calls to CISTPL_VERS_1 and CISTPL_MANFID now set BIND_FN_ALL. This was already the case for calls to CISTPL_LONGLINK_MFC. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2008-08-31pcmcia: remove unused argument to pcmcia_parse_tuple()Dominik Brodowski
Since we're just parsing the tuple being passed to this function, we don't need any device-specific information. Also, remove the call to pcmcia_validate_cis() from pcmciamtd.c, since it is already called by the PCMCIA core. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>

2008-08-23pcmcia: deprecate CS_NO_MORE_ITEMSDominik Brodowski
CS_NO_MORE_ITEMS is returned by the CIS tuple reading and parsing code if the end of a tuple chain is reached. As at least one PCMCIA driver relies on matching this return value, replace it with -ENOSPC which is now uniquely used for this purpose within the in-kernel pcmcia subsystem.

2005-07-07[PATCH] pcmcia: remove client services versionPavel Roskin
The Linux PCMCIA code has some data that was apparently used (or meant to be used) to ensure that only proper client drivers are loaded. This is now ensured (to a certain degree) by the fact that the most client drivers are part of the kernel. Also, the version information has not been updated despite major changes in PCMCIA API. This has made it meaningless. This patch removes servinfo_t and pcmcia_get_card_services_info. They are not used in any userspace utilities such as pcmcia-cs and pcmciautils. drivers/pcmcia/pcmcia_ioctl.c is adjusted accordingly. CS_RELEASE and CS_RELEASE_CODE are removed. include/pcmcia/version.h is empty now. It will be removed later, but for now it's left in the tree to avoid touching all PCMCIA clients. The only driver that needs to be changed is drivers/scsi/pcmcia/nsp_cs.c, which uses CS_RELEASE_CODE.
