[libcamera-devel] [PATCH] qcam: Clear the pool of free requests upon stopCapture()

[Paul Elder]

To enable reusing Request objects, we kept a pool of free Requests. This
pool was not cleared upon stopping capture, however, which caused a
segfault when switching to another camera. Fix this by clearing the
Request pool on stopCapture().

Reuse Request")
