* [tree-wide] finally take no_llseek outAl Viro2024-09-275-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | 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.

For hard-wired designs that omit the regulator from their device trees regulator subsystem will create a dummy instance. This may introduce unnecessary delay of 100us in case of dummy regulator, but if it is important the driver should be marked as using asynchronous probing to avoid even longer delays waiting for the command completions. Also use usleep_range() instead of udelay() to avoid spinning.

Instead of accounting for the leading byte by increasing offset of each field in contacts by one introduce a pointer to contact data and point it appropriately. This avoids awkward constructs like: point.prblty = payload[9 * i + 9]; which makes it seem like there is off-by-one error, in favor of more straightforward: point.prblty = p[8]; Tested-by: Andreas Kemnade <andreas@kemnade.info> # Tolino Shine2HD Link: https://lore.kernel.org/r/20240824055047.1706392-11-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
