2024-11-18rtc: brcmstb-waketimer: don't include 'pm_wakeup.h' directlyWolfram Sang
The header clearly states that it does not want to be included directly, only via 'device.h'. 'platform_device.h' works equally well. Remove the direct inclusion.

2024-11-18rtc: ab-eoz9: fix abeoz9_rtc_read_alarmAlexandre Belloni
abeoz9_rtc_read_alarm assumes we always read the alarm in 12-hour mode while abeoz9_rtc_set_alarm will always set it in 24-hour mode. We could support 12-hour mode in both functions but it seems very unlikely that the RTC would be set to 12-hour mode now as the driver has been setting it to 24-hour mode for a while now. The setting is undefined at power-up and unchanged by subsequent resets which doesn't help us.

If the __rtc_read_time call fails,, the struct rtc_time tm; may contain uninitialized data, or an illegal date/time read from the RTC hardware.

Instead of calculating the number of full days since Sunday with (days + 4) % 7, read (and write) that to the RTC Day-of-week Time Counter register (RTC_TC_DOW). Some transformation (addition and subtraction for set/get) is still done, as this register's range is [1..7], while the tm_wday in struct tm's range is [0..6]. Please note that this was added only to set_time() and read_time() callbacks because set_alarm() and read_alarm() are setting a bit in RTC_AL_MASK to ignore DOW for RTC HW alarms for unknown reasons.

Also remove the RTC_MIN_YEAR_OFFSET addition and subtraction in callbacks set_time() and read_time() respectively, as now this is already done by the API.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/rtc to use .remove(), with the eventual goal to drop struct platform_driver::remove_new().

2024-09-28fbdev: sisfb: Fix strbuf array overflowAndrey Shumilin
The values of the variables xres and yres are placed in strbuf. These variables are obtained from strbuf1. The strbuf1 array contains digit characters and a space if the array contains non-digit characters. Then, when executing sprintf(strbuf, "%ux%ux8", xres, yres); more than 16 bytes will be written to strbuf. It is suggested to increase the size of the strbuf array to 24.

2024-09-27[tree-wide] finally take no_llseek outAl Viro
no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\<no_llseek\>/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.
