I don't want to mention about braces.
However, I said that you should keep the indentation.

Your original patch

+		if (cfi->cfiq->BufWriteTimeoutTyp &&
+			cfi->cfiq->BufWriteTimeoutMax){
+			cfi->chips[i].buffer_write_time_max =
+				1<<(cfi->cfiq->BufWriteTimeoutTyp +
+					cfi->cfiq->BufWriteTimeoutMax);
+			} else {
+				cfi->chips[i].buffer_write_time_max = 0;
+				}
+		cfi->chips[i].buffer_write_time_max =
+			((cfi->chips[i].buffer_write_time_max>= 2000)
+			 ? cfi->chips[i].buffer_write_time_max : 2000);

My suggestion is as follows: 

+		if (cfi->cfiq->BufWriteTimeoutTyp &&
+			cfi->cfiq->BufWriteTimeoutMax){
+			cfi->chips[i].buffer_write_time_max =
+				1<<(cfi->cfiq->BufWriteTimeoutTyp +
+					cfi->cfiq->BufWriteTimeoutMax);
+		} else {
+			cfi->chips[i].buffer_write_time_max = 0;
+		}
+		cfi->chips[i].buffer_write_time_max =
+			((cfi->chips[i].buffer_write_time_max>= 2000)
+			 ? cfi->chips[i].buffer_write_time_max : 2000);

Braces? I have no idea. Actually, I prefer to use braces for the
readability. However, according to the Document/CodingStyle, 
these braces are unnecessary.

However, one thing is clear; 'if' and 'else' should use the same
indentation level as below.

1. 
	if(){
		...
	} else {
		...
	}

2.
		if(){
			...
		} else {
			...
		}

3.

			if(){
				...
			} else {
				...
			}
