Why don't use git protocol instead of link to fetched sources?

Here is my updated recipe:

# comment
SUMMARY = "ST-Link firmware flasher"
DESCRIPTION = ""
SECTION = "examples"
LICENSE = "MIT"
LIC_FILES_CHKSUM =
"file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

DEPENDS = "libusb pkgconfig"

SRCREV = "55c057296ad15fa6de9909206098bd4eed8f6311"

PV = "1.3.1+git${SRCPV}"

SRC_URI = "git://github.com/texane/stlink.git"

SRC_URI[md5sum] = "99fa2b1de041f62b7285a8f1870c891b"
SRC_URI[sha256sum] =
"8545752efe2be13c6dbadec48c93cd72be448147f38f0fe44050c0416827ca37"

S = "${WORKDIR}/git"

inherit cmake

Also it is necessary to patch a stlink before to pass configuration phase like:
diff --git a/CMakeLists.txt b/CMakeLists.txt
index afa7fde..4d2db6c 100644

Then it still fails to compile but I tried to compile it for arm so
maybe this is the reason. Hope it helps a bit ;).
