Subject: media: staging: atomisp: gc2235: constify acpi_device_id
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e9e8c1cd18dcc047ad9b9d640fa5b198a096df90;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

media: staging: atomisp: gc2235: constify acpi_device_id

acpi_device_id are not supposed to change at runtime. All functions
working with acpi_device_id provided by <acpi/acpi_bus.h> work with
const acpi_device_id. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  10754	   1360	      4	  12118	   2f56
drivers/staging/media/atomisp/i2c/gc2235.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  10818	   1296	      4	  12118	   2f56
drivers/staging/media/atomisp/i2c/gc2235.o
