<br />
efi/capsule-loader: fix incorrect allocation size<br />
<br />
gcc-14 notices that the allocation with sizeof(void) on 32-bit architectures<br />
is not enough for a 64-bit phys_addr_t:<br />
<br />
drivers/firmware/efi/capsule-loader.c: In function &#39;efi_capsule_open&#39;:<br />
drivers/firmware/efi/capsule-loader.c:295:24: error: allocation of insufficient size &#39;4&#39; for type &#39;phys_addr_t&#39; {aka &#39;long long unsigned int&#39;} with size &#39;8&#39; [-Werror=alloc-size]<br />
295 | cap_info->phys = kzalloc(sizeof(void *), GFP_KERNEL);<br />
