| * i2c: Use a separate mutex for userspace client listsJean Delvare2010-08-111-6/+7
| | | | | | | | | | | | | | | | | | Moving userspace-instantiated clients to separate lists wasn't nearly enough to avoid deadlocks in multiplexed bus cases. We also want to have a dedicated mutex to protect each list. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Michael Lawnick <ml.lawnick@gmx.de>

| | | | | | | | | | | | | | | | Make i2c_default_probe self-sufficient, so that callers don't have to do functionality checks themselves. This ensures everything is and will stay consistent. Signed-off-by: Jean Delvare <khali@linux-fr.org>
| * i2c: Drop dummy variableJean Delvare2010-08-111-3/+2
| | | | | | | | | | | | | | | | Now that bus_for_each_drv() is no longer __must_check, we can drop the dummy variable that was used to store the returned value. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Justin P. Mattock <justinmattock@gmail.com>
| * i2c: Move adapter locking helpers to i2c-coreJean Delvare2010-08-111-5/+34
| | | | | | | | | | | | | | | | | | | | Uninline i2c adapter locking helper functions, move them to i2c-core, and use them in i2c-core itself. The functions are still exported for external users. This makes future updates to the locking model (which will be needed for multiplexing support) possible and transparent.

Note that in the second case, the ++i is no longer necessary, as the last value is already freed if needed by the call to memdup_user.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is one of the most interesting users of module parameters in the tree, so weaning it off the old-style non-const module_param_call scheme is a useful exercise. I was confused by set_param_int/get_param_int (vs. the normal param_set_int and param_get_int), so I renamed set_param_int to set_param_timeout, and re-used param_get_int directly instead of get_param_int. I also implemented param_check_wdog_ifnum and param_check_timeout, so now the ifnum_to_use and timeout/pretimeout parameters can just use plain module_param().

| * | param: use ops in struct kernel_param, rather than get and set fns directlyRusty Russell2010-08-113-18/+29
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is more kernel-ish, saves some space, and also allows us to expand the ops without breaking all the callers who are happy for the new members to be NULL. The few places which defined their own param types are changed to the new scheme (more which crept in recently fixed in following patches). Since we're touching them anyway, we change get() and set() to take a const struct kernel_param (which they really are). This causes some harmless warnings until we fix them (in following patches). To reduce churn, module_param_call creates the ops struct so the callers don't have to change (and casts the functions to reduce warnings). The modern version which takes an ops struct is called module_param_cb.

Min/Max Voltage. max8998_set_voltage had been using the voltage value of min ( voltage[i] >= max_vol , i ) This is corrected to use: min ( voltage[i] >= min_vol , i ) 2. Ramp Up Delay. max8998_set_voltage should provide delay for BUCK1/2 if ENRAMP is on. It reads RAMP value from ONOFF4 register to determine RAMP delay length. However, when max8998_set_voltage's new voltage is lower than the previous, we don't care because it does not deteriorate the stability.
