Subject: rdtech-um: eliminate redundant data types in memory allocation
X-Git-Url: https://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=bc9aa94b92c5ac0271769af4605992d7a38e65bc

rdtech-um: eliminate redundant data types in memory allocation

Just allocate the size of the involved variable. Eliminate redundant
data type specs where inconsistency would go unnoticed.

Link the device context earlier to the device instance while we are
here. Immediately after allocation of the dynamic memory so that the
relation remains obvious.
