2016-03-18ipmi_ssif: Fix logic around alert handlingCorey Minyard
There was a mistake in the logic, if an alert came in very quickly it would hang the driver. Signed-off-by: Corey Minyard <cminyard@mvista.com>
2016-01-12char: ipmi: Drop owner assignment from i2c_driverKrzysztof Kozlowski
i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com>
2015-10-24char: ipmi: ipmi_ssif: Replace timeval with timespec64Amitoj Kaur Chawla
This patch replaces timeval with timespec64 as 32 bit 'struct timeval' will not give current time beyond 2038. The patch changes the code to use ktime_get_real_ts64() which returns a 'struct timespec64' instead of do_gettimeofday() which returns a 'struct timeval' This patch also alters the format string in pr_info() for now.tv_sec to incorporate 'long long' on 32 bit architectures.

2015-09-03ipmi:ssif: Add a module parm to specify that SMBus alerts don't workCorey Minyard
They are broken on some platforms, this gives people a chance to work around it until the firmware is fixed. Signed-off-by: Corey Minyard <cminyard@mvista.com>

Constify the ACPI device ID array, it doesn't need to be writable at runtime. Signed-off-by: Mathias Krause <minipli@googlemail.com> Signed-off-by: Corey Minyard <cminyard@mvista.com>

2015-05-05ipmi: Fix multi-part message handlingCorey Minyard
Lots of little fixes for multi-part messages: The values was not being re-initialized, if something went wrong handling a multi-part message and it got left in a bad state, it might be an issue. The commands were not correct when issuing multi-part reads, the code was not passing in the proper value for commands. Also clean up some minor formatting issues. Get the block number from the right location, limit the maximum send message size to 63 bytes and explain why, and fix some minor sylistic issues. Signed-off-by: Corey Minyard <cminyard@mvista.com>
2015-05-05ipmi: Add alert handling to SSIFCorey Minyard
The SSIF interface can optionally have an SMBus alert come in when data is ready. Unfortunately, the IPMI spec gives wiggle room to the implementer to allow them to always have the alert enabled, even if the driver doesn't enable it. So implement alerts. If you don't in this situation, the SMBus alert handling will constantly complain. Signed-off-by: Corey Minyard <cminyard@mvista.com>

2015-05-05ipmi: Remove incorrect use of seq_has_overflowedJoe Perches
commit d6c5dc18d863 ("ipmi: Remove uses of return value of seq_printf") incorrectly changed the return value of various proc_show functions to use seq_has_overflowed(). These functions should return 0 on completion rather than 1/true on overflow. 1 is the same as #define SEQ_SKIP which would cause the output to not be emitted (skipped) instead. This is a logical defect only as the length of these outputs are all smaller than the initial allocation done by the seq filesystem.

2015-05-05ipmi:ssif: Ignore spaces when comparing I2C adapter namesCorey Minyard
Some of the adapters have spaces in their names, but that's really hard to pass in as a module or kernel parameters. So ignore the spaces. Signed-off-by: Corey Minyard <cminyard@mvista.com>
2015-05-05ipmi_ssif: Fix the logic on user-supplied addressesCorey Minyard
Returning zero is success. Signed-off-by: Corey Minyard <cminyard@mvista.com>
2015-04-10ipmi_ssif: Use interruptible completion for waiting in the threadCorey Minyard
The code was using an normal completion, but that caused stuck task errors after a while. Use an interruptible one to avoid that. Signed-off-by: Corey Minyard <cminyard@mvista.com>
2015-02-19ipmi: Remove uses of return value of seq_printfJoe Perches
The seq_printf like functions will soon be changed to return void. Convert these uses to check seq_has_overflowed instead. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Corey Minyard <cminyard@mvista.com>
2015-02-19char: ipmi: Remove obsolete cleanup for clientdataWolfram Sang
