[libcamera-devel] [PATCH] ipa: rpi: agc: Fix bug where AeLocked was never getting set

[David Plowman]

The recent change where time-filtering is done before sorting out the
digital gain means that the target exposure without digital gain is no
longer set, breaking the 'AeLocked' calculation.

We can use the regular (full) target exposure instead.
