Remove typedefs keyword and rename identifiers appropriately. Remove volatile from union usb_regs_access. Update related files. Signed-off-by: Haneen Mohammed --- v8: Edit subject line. v7: nothing. v6: merge two patches into one. removal of typedefs and of volatile. v5: nothing v4: Replace struct with volatile union for usb_reg_access. v3: Removed all typedefs and created patchset from emxx_udc. v2: Removed typedefs appropriately and changed related file. drivers/staging/emxx_udc/emxx_udc.c | 60 ++++++++++++++++++------------------- drivers/staging/emxx_udc/emxx_udc.h | 26 ++++++++-------- 2 files changed, 43 insertions(+), 43 deletions(-) diff --git a/drivers/staging/emxx_udc/emxx_udc.c b/drivers/staging/emxx_udc/emxx_udc.c index 4be646c..f2ddad3 100644 --- a/drivers/staging/emxx_udc/emxx_udc.c +++ b/drivers/staging/emxx_udc/emxx_udc.c @@ -201,7 +201,7 @@ static u32 _nbu2ss_get_begin_ram_address(struct nbu2ss_udc *udc) u32 num, buf_type;
