[libcamera-devel] [PATCH v8 11/17] lc-compliance: Move buffer allocation to separate function

Move buffer allocation to its own function and with an optional count
argument so tests can specify how many buffers to allocate. When count
is omitted, allocate MinimumRequests buffers.

Changes in v8:
- Made SimpleCapture::allocateBuffers() a single function with an optional parameter

Changes in v5:
- New
