[libcamera-devel] [PATCH v7 03/11] lc-compliance: Move buffer allocation to separate function

[Nícolas F. R. A. Prado]

Move buffer allocation to its own function and with a count argument so
tests can specify how many buffers to allocate.

Also add an overloaded function with no arguments and that allocates
MinNumRequests buffers for easier use by current tests.
