pcmcia: Add error handling for add_interval() in do_validate_mem()

2025-08-16T13:49:58+00:00

In the do_validate_mem(), the call to add_interval() does not handle errors. If kmalloc() fails in add_interval(), it could result in a null pointer being inserted into the linked list, leading to illegal memory access when sub_interval() is called next. This patch adds an error handling for the add_interval(). If add_interval() returns an error, the function will return early with the error code.

pcmcia: remove PCCARD_IODYN

2025-08-16T13:37:47+00:00

The config PCCARD_IODYN was last used in the config option PCMCIA_M8XX with its m8xx_pcmcia driver. This driver was removed with commit 39eb56da2b53 ("pcmcia: Remove m8xx_pcmcia driver"), included in v3.17, back in 2014. Since then, the config PCCARD_IODYN is unused. Remove the config option, the corresponding file included with this config and the corresponding definition in the pcmcia header file. Signed-off-by: Lukas Bulwahn Signed-off-by: Dominik Brodowski

pcmcia: ds: Emphasize "really" epizeuxis

2025-08-16T13:36:08+00:00

pcmcia_dev_present() comment writes about small timeframe where the function returns NULL (racy condition), in epizeuxis device. In the past, it tripped contributors who misunderstood it for "really" duplicate ([1], [2]). Add comma between "really" words to emphasize the epizeuxis.

pcmcia: Fix a NULL pointer dereference in __iodyn_find_io_region()

2025-08-16T13:31:00+00:00

In __iodyn_find_io_region(), pcmcia_make_resource() is assigned to res and used in pci_bus_alloc_resource(). There is a dereference of res in pci_bus_alloc_resource(), which could lead to a NULL pointer dereference on failure of pcmcia_make_resource(). Fix this bug by adding a check of res.

pcmcia: omap_cf: Mark driver struct with __refdata to prevent section mismatch

As described in the added code comment, a reference to .exit.text is ok for drivers registered via platform_driver_probe(). Make this explicit to prevent the following section mismatch warning WARNING: modpost: drivers/pcmcia/omap_cf: section mismatch in reference: omap_cf_driver+0x4 (section: .data) -> omap_cf_remove (section: .exit.text) that triggers on an omap1_defconfig + CONFIG_OMAP_CF=m build.
