[PATCH 0/3] Mop-up last remaining patches for Misc

[PATCH 0/3] Mop-up last remaining patches for Misc

[Lee Jones]

These required fix-ups or were waiting on review.

Lee Jones (3):
  misc: vmw_vmci_defs: Mark 'struct vmci_handle VMCI_ANON_SRC_HANDLE' as
    __maybe_unused
  misc: eeprom: at24: Tell the compiler that ACPI functions may not be
    used
  misc: cxl: flash: Remove unused variable 'drc_index'

[PATCH 1/3] misc: vmw_vmci_defs: Mark 'struct vmci_handle VMCI_ANON_SRC_HANDLE' as __maybe_unused

[Lee Jones]

vmw_vmci_defs.h is included by multiple source files.  Some of which
do not make use of 'struct vmci_handle VMCI_ANON_SRC_HANDLE' rendering
it unused.  Ensure the compiler knows that this is in fact intentional
by marking it as __maybe_unused.  This fixes the following W=1 warnings:

 In file included from drivers/misc/vmw_vmci/vmci_context.c:8:
 include/linux/vmw_vmci_defs.h:162:33: warning: ‘VMCI_ANON_SRC_HANDLE’ defined but not used [-Wunused-const-variable=]

[Lee Jones]

... as is the case when !CONFIG_ACPI.

[PATCH v2 3/3] misc: cxl: flash: Remove unused variable 'drc_index'

[Lee Jones]

Keeping the pointer increment though.

Fixes the following W=1 kernel build warning:

 drivers/misc/cxl/flash.c: In function ‘update_devicetree’:
 drivers/misc/cxl/flash.c:178:16: warning: variable ‘drc_index’ set but not used [-Wunused-but-set-variable]
