Subject: nvme-pci: remove an unnecessary initialization in HMB code
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6fbcde6691b514faa963c60f5537332530f1bf0a;p=openwrt%2Fstaging%2Fblogic.git

nvme-pci: remove an unnecessary initialization in HMB code

The local variable __size__ will be set a bit later in a for-loop.
Remove the explicit initialization at the beginning of this function.
