When updating the callbacks, adding their kernel-doc was forgotten. Add it now. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Closes: https://lore.kernel.org/r/20240712165527.75e4ddc9@canb.auug.org.au Fixes: a93c2e5fe766 ("i2c: reword i2c_algorithm according to newest specification") Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> --- Andi, this is the minimal fix for the the regression reported by Stephen. Please apply it on top of the rewording series. There will be more fixes in this paragraph but these should go better via my tree, I guess, after I pulled yours. include/linux/i2c.h | 20 +++++++++++++------- 1 file changed, 13 insertions(+), 7 deletions(-)
