The patch titled
Subject: mtd: rawnand: vf610_nfc: add initializer to avoid -Wmaybe-uninitialized
has been removed from the -mm tree. Its filename was
mtd-rawnand-vf610_nfc-add-initializer-to-avoid-wmaybe-uninitialized.patch
This patch was dropped because it was merged into mainline or a subsystem tree

From: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx>
Subject: mtd: rawnand: vf610_nfc: add initializer to avoid -Wmaybe-uninitialized
This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common place.
We need to eliminate potential issues beforehand.
Kbuild test robot has never reported -Wmaybe-uninitialized warning for
this probably because vf610_nfc_run() is inlined by the x86 compiler's
inlining heuristic.
If CONFIG_OPTIMIZE_INLINING is enabled for a different architecture and
vf610_nfc_run() is not inlined, the following warning is reported:
drivers/mtd/nand/raw/vf610_nfc.c: In function `vf610_nfc_cmd':
drivers/mtd/nand/raw/vf610_nfc.c:455:3: warning: `offset' may be used uninitialized in this function [-Wmaybe-uninitialized]
vf610_nfc_rd_from_sram(instr->ctx.data.buf.in + offset,
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
nfc->regs + NFC_MAIN_AREA(0) + offset,
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
trfr_sz, !nfc->data_access);
~~~~~~~~~~~~~~~~~~~~~~~~~~~
