rtc: ds1307: fix Wvoid-pointer-to-enum-cast warning

2023-08-15T23:32:08Z

'type' is an enum, thus cast of pointer on 64-bit compile test with W=1 causes: rtc-ds1307.c:1747:18: error: cast to smaller integer type 'enum ds_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20230810103902.151145-1-krzysztof.kozlowski@linaro.org Signed-off-by: Alexandre Belloni

rtc: Switch i2c drivers back to use .probe()

2023-06-06T21:29:37Z

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

rtc: ds1307: Convert to i2c's .probe_new()

2023-01-09T22:03:56Z

.probe_new() doesn't get the i2c_device_id * parameter, so determine that explicitly in the probe function. Signed-off-by: Uwe Kleine-König Link: https://lore.kernel.org/r/20221118224540.619276-561-uwe@kleine-koenig.org Signed-off-by: Alexandre Belloni

rtc: ds1307: use sysfs_emit() to instead of scnprintf()

2022-12-15T22:34:31Z

Follow the advice of the Documentation/filesystems/sysfs.rst and show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space.

rtc: Include when appropriate

2022-11-15T20:01:51Z

The kstrto() functions have been moved from kernel.h to kstrtox.h. So, include the latter directly in the appropriate files.

rtc: ds1307: replace HAS_ALARM by RTC_FEATURE_ALARM

2021-04-29T21:04:13Z

The core now has RTC_FEATURE_ALARM for the driver to indicate whether alarms are available. Use that instead of HAS_ALARM to ensure the alarm callbacks are not even called.
