char/mwave: drop it

2025-12-29T10:53:38+00:00

When I tried to clean up the driver a bit, Arnd noted: > According to thinkwiki.de, the 3780i modem was only used in a > couple of Thinkpad models that are now over 25 years old, using > Pentium II processors, and they all have a physical RS232 port > that can be used to connect an external modem instead. > > Maybe we can just retire this driver? So instead of the clean up, drop the driver altogether.

char/mwave: drop typedefs

2025-11-26T13:40:46+00:00

typedefs are unnecessary here. They rather obfuscate the code than help. So drop them and use the types directly. Signed-off-by: Jiri Slaby (SUSE) Acked-by: Arnd Bergmann Link: https://patch.msgid.link/20251119091949.825958-7-jirislaby@kernel.org Signed-off-by: Greg Kroah-Hartman

char/mwave: drop printk wrapper

2025-11-26T13:40:46+00:00

PRINTK_ERROR() + KERN_ERR_MWAVE are just wrappers around printk() with a prefix. Instead, pr_fmt() can be used. Drop the former and use the latter.

char/mwave: remove printk tracing

2025-11-26T13:40:46+00:00

The printk tracing makes the code hard to follow for no good benefit. Everyone can use dynamic tracing and/or kprobes. Drop this unreadable bloatware too.

char/mwave: turn tp3780I_Cleanup() into void function

2021-03-24T07:26:30+00:00

This function always return '0' and no callers use the return value. So make it a void function. This eliminates the following coccicheck warning: ./drivers/char/mwave/tp3780i.c:182:5-11: Unneeded variable: "retval".

char/mwave: remove custom BOOLEAN type

2016-08-31T12:22:49+00:00

The mwave driver has its own macros for the BOOLEAN type and the TRUE/FALSE values. This is redundant because the kernel already has bool/true/false, and it clashes with the ACPI headers that also define these types. The linux/acpi.h header is now included implicitly from mwave through the mc146818rtc.h header, as reported by Stephen Rothwell: In file included from drivers/char/mwave/smapi.c:51:0: drivers/char/mwave/smapi.h:52:0: warning: "TRUE" redefined #define TRUE 1 ^ In file included from include/acpi/acpi.h:58:0, from include/linux/acpi.h:33, from include/linux/mc146818rtc.h:21, from drivers/char/mwave/smapi.c:50: include/acpi/actypes.h:438:0: note: this is the location of the previous definition #define TRUE (1 == 1) ^ This removes the private types from mwave and uses the standard types instead.

mwave: fix info leak in mwave_ioctl()

2013-07-09T17:33:28+00:00

Smatch complains that on 64 bit systems, there is a hole in the MW_ABILITIES struct between ->component_count and ->component_list[]. It leaks stack information from the mwave_ioctl() function. I've added a memset() to initialize the struct to zero. Signed-off-by: Dan Carpenter Cc: Greg KH Cc: Jiri Kosina Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

arm/mach-integrator/time.c, mwave: revert portions of recent irq cleanups

2008-04-24T12:35:37+00:00

The recent irq cleanups for arch/arm/mach-integrator/time.c and drivers/char/mwave/tp3780i.c changed the request_irq() dev_id parameter, but neglected to change the matching free_irq() parameter, thus creating a bug upon irq de-registration. Given that the impetus for the changes is not yet accepted upstream, it is best to revert the irq cleanups. Mostly. A comment is added to time.c to reduce future confusion, of type that led to my time.c cleanup in the first place. Signed-off-by: Jeff Garzik
