Prepare for platform specific callbacks usage: * Rearrange code for directly use struct nct6775_sio_data in superio_*() functions. * Use superio function pointers in nct6775_sio_data struct instead direct calls. * Use nct6775 function pointers in struct nct6775_data instead direct calls. BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=204807 Signed-off-by: Denis Pauk <pauk.denis@xxxxxxxxx> Co-developed-by: Bernhard Seibold <mail@xxxxxxxxxxxxxxxxxxx> Signed-off-by: Bernhard Seibold <mail@xxxxxxxxxxxxxxxxxxx> Cc: Andy Shevchenko <andriy.shevchenko@xxxxxxxxx> Cc: Guenter Roeck <linux@xxxxxxxxxxxx> --- Changes in v5: - Without changes. Changes in v4: - Fix naming conflict with inb, outb by add sio prefix to callbacks in nct6775_sio_data. Changes in v3: - Use nct6775 function pointers in struct nct6775_data instead direct calls. - make function declarations one line. Changes in v2: - Split changes to separate patches. - Rearrange code for directly use struct nct6775_sio_data in superio_*() functions. --- drivers/hwmon/nct6775.c | 465 +++++++++++++++++++++------------------- 1 file changed, 247 insertions(+), 218 deletions(-) diff --git a/drivers/hwmon/nct6775.c b/drivers/hwmon/nct6775.c index 5bd15622a85f..d813a7478f59 100644 --- a/drivers/hwmon/nct6775.c +++ b/drivers/hwmon/nct6775.c @@ -133,30 +133,46 @@ MODULE_PARM_DESC(fan_debounce, "Enable debouncing for fan RPM signal");
